anvil Posted March 30, 2007 Posted March 30, 2007 I posted this on another msg board when you were down yesterday,, but got no help.. hopefully you can help me here. I am new to imgburn, but find it very user friendly,,and thought i had it figured out... I am trying to back up avi files from my camcorder onto verbatum DVD+R DL double layer disks. I did a movie first to test out the burn and it went fine. the burn went fine and was verified but when i tried to play the individual avi files from the disk, they were jerkey and very slow. some got error msgs from my player (latest version of mplayer classic). here is the data from the rt window in imgburn ver 2.3.0.0. I also copied the files to my desktop,, but still had the same problem. all these files play fine on my hd after transferring them from my camcorder (miniDV) to HD (avi). i burned another two or three movies off my HD to dual layer disks (same as above) with no problems.. i can only guess that i have something not set up correct to burn a dual layer data disk.. i don't seem to remember seeing the screen to select the breakpoint between layers.. sorry but thats about the only hint i can give...

anvil Posted March 30, 2007 Author Posted March 30, 2007 I did some more research on your site,, and actually found nothing on this problem,, But,, i noticed you suggest that you burn dual layer disks at 2.4x speed. I did burn all my movies (which burned fine) and the faulty data disk at 4x. could this be the problem? even tho all disks were verified good burn? anvil
chewy Posted March 30, 2007 Posted March 30, 2007 I have never had this problem with good single layer media, still don't trust dual layer enough A new hard drive would be much more efficient for backup of this data than dual layer media
anvil Posted March 30, 2007 Author Posted March 30, 2007 chewy,, thats an option i have thought of a well,, perhaps a large USB that i can use just for these files.. they are going to be for a documentary on building my new shop,, Lol,, a very low tech hands on stone,Iron,and Log Blacksmith shop,,, I am a man with a high tech hobby (my 'puter) and a very low tech Lifestyle,, is the best way to describe my work.. but i would still like to know what is causing this problem... anvil
anvil Posted March 30, 2007 Author Posted March 30, 2007 has that liteon seen a lot of use? Ive had it about a year.. average use. I seem to go thru phases of use. Lol,, like when the ole HD's are getting full, i burn all the junk off anvil
chewy Posted March 31, 2007 Posted March 31, 2007 If it's getting over 500 burns it might be time for a clean/overhaul or replacement Some drives do a few hundred, others almost 1000 burns
polopony Posted March 31, 2007 Posted March 31, 2007 I've gone almost 2000 with my NEC3500 its been one sweet drive ,I only use Verbs and Yudens, now I have to identify all the discs and get them into cases maybe after my nap
anvil Posted April 4, 2007 Author Posted April 4, 2007 If it's getting over 500 burns it might be time for a clean/overhaul or replacement Some drives do a few hundred, others almost 1000 burns well maby that is the case. i did notice that when i burnt my last single layed dvd's i got some coasters until i slowed the burn speed down to 6x thanks all for the leads anvil
moondogger Posted April 4, 2007 Posted April 4, 2007 (edited) Anvil.... The problem is most likely that you can not read from a (dual layer) DVD fast enough to sustain smooth video playback. There is nothing wrong with the .avi files nor the disc. If you tried to copy the files back to the hard drive and play them back from there you will see that they are fine. Use the (dual layer) DVD for storage purposes only. Edited April 4, 2007 by moondogger
chewy Posted April 4, 2007 Posted April 4, 2007 good point, wonder what the play time is for those large avi's per gig
anvil Posted April 7, 2007 Author Posted April 7, 2007 moondogger,, hmmm i thru the disk away,,and don't remember if i copied from dvd to disk,,and tried to play the file.. I will reburn and give it a try. also i will burn at 2.4x. I can play dual layer dvd movies with no problem,,and when i back up a movie onto dual layer,, i can play them from this drive. chewy,,, a dv tape is about an hour of video and is 17 gig in size.. fits on two dual layer dvds with no problem. However they are many segments, not one continuous video file. every time you stop or pause it creates a new file. So they are different sizes. I wonder if I made a mistake in burning. I do not remember the screen coming up for me to select the layer break. Is this because its a data disk and not a movie? Or did i miss a step. anvil
mmalves Posted April 7, 2007 Posted April 7, 2007 I wonder if I made a mistake in burning. I do not remember the screen coming up for me to select the layer break. Is this because its a data disk and not a movie? That screen only appears when DVD-Video content is detected; for normal data DVDs the layer break is calculated automatically.
moondogger Posted April 7, 2007 Posted April 7, 2007 Yes, you should be able to playback dual layer movies... that's how they designed it. Playback rate of a DVD Movie is about 10 mb per second max, thats roughly 4.5 GB per hour. At 17 GB (DV) per hour your pushing way past the read rate your drive can handle. It would need to SUSTAIN a 4X read speed to smoothly playback DV video. If it can't your video will studder badly.
chewy Posted April 8, 2007 Posted April 8, 2007 I guess I would want a big e-sata drive to save those avi's
anvil Posted April 8, 2007 Author Posted April 8, 2007 Great info here,, thanks much.. actually my tapes are 80 min tapes and this creates a number of avi files running 17 gig total. So even using two dual layer disks,, aprox 8 gig of data on each,, will cause this problem? (obviously, i think) If i instead use 4 single layer DVD's, then i will have around 4 gig per dvd. will this solve the stuttering problem? wow.. i digress here a minute,, The Internet is just an incredible place.. the Sh-t you have to go thru to do what you want with these relativly inexpensive high tech toys.. . and all the info you need is here on the internet,, just for the time to search,,and the input from good people, This is a golden time,, may it last forever... Yea,, i think a large e-sata drive will be on my list for backups of my film clips.. and i think i will use at least two different forms of backup,, just to be safe. Tape backup is the most expensive,most reliable, but least user friendly because you have to retransfer to the computer to do any editing,,and this is done in realtime. DVD's\Hd's are the most convenient,,and are very cost efficient, but their reliability over time is still unknown,, Lol,, just how do they know a new dvd will last 100 years? sheesh,, DVD's are hardly 10 years old,, more or less.. Hard drives,, alas,, are inexpensive, large, and prone to crash.. I already lost my first three hours of video on a Hitachi internal,, not 3 months old... Now all my clips are on my two large SATA western digital drives,, and ,, and,, sheesh,, but i gots to do something,,, my drives are getting full!! Thanks anvil
Shamus_McFartfinger Posted April 8, 2007 Posted April 8, 2007 Hard drives,, alas,, are inexpensive, large, and prone to crash.. I already lost my first three hours of video on a Hitachi internal,, not 3 months old... Prone to crash? That's a big claim. Admittedly, some fail. Others, like the trusty HD in my Amiga 4000 have been running fine for the past 10 years. Heat is one of the big killers of harddrives. Keep 'em cool and they last longer. Cleaning the inside of the case every couple of months with compressed air will get rid of the insulating crud that builds up on everything over time - keeping it cool. Use 5400 rpm drives instead of 7200 rpm. They're a bit slower but they run cooler. Buy Seagate drives - they run cooler than everything else (which is why they work best in a PS2). Buy a Coolermaster PC case or something similar that has heaps of air flow. etc... etc... Now all my clips are on my two large SATA western digital drives,, and ,, and,, sheesh,, but i gots to do something,,, my drives are getting full!! Spare a thought for lmao2k as he has 13TB to manage.
anvil Posted April 8, 2007 Author Posted April 8, 2007 aaarg,,, 13TB!!! and i thought i had problems!! anvil
anvil Posted May 29, 2007 Author Posted May 29, 2007 I thought i would add a bit more here to this problem. It is not a problem with IB... I have no problem with Media player Classic playing these avi files that i have copied to my hd directly from my camera. the problem is when i burn them to a dvd,, double layer or single. then i cannot play them with MPC. I thought it was a burn problem. However, i saw a post here that spoke of VLC media player and thought i would give it a try. I had made a short test avi clip in anothe program,,and played it back with MPC..and alas I had the Stutters again.. like two low a frame rate in a game. By chance i played it in VLC,, and had no problems... So i decided to try my latest attempts at burning these files to dvd,,( I reburned them on both a dual and single layer dvd), initially i thought they were coasters,, so did a David Letterman,, and sailed them across the room twards my trusty Woodburner,,, well in VLC, the problems were still there,,but not nearly as bad,, just an occasional stutter. next i decided to play the avi from my hd,, then replayed the same file directly from my dvd's. Strangely enough,, I had no problem with either. I have no clue as to why when i play the file from hd,, then replay from dvd it works "as advertised"!! So next i added the avi files directly from dvd into my editing software,,and played them there (Premiere Pro 2). Again they played flawlessly. Go figure.. I have not tried playback with any commercial players,, as i gave them up long ago for MPC and now VLC,so don't know if that makes a difference.. just wanted to add this in case anybody else has a similer problem.. anvil
