DOH! Yes, the 'Buffer' should empty before the 'Device Buffer' but it doesn't work like that. The 'Device Buffer' is inside the actual drive (obviously) and the 'Buffer' is in your systems memory (or part of the swap file). I don't write to the 'Device Buffer', I send data to the drive... IT controls the device buffer. If there's a problem getting data from the 'Buffer' to the 'Device Buffer' - i.e. the machine is busy or the I/O subsystem is busy with other things - the 'Device Buffer' will empty out. There's not a change I could make to ImgBurn to prevent that, it's out of my control. Blame your system as a whole. High priority should be enough, you wouldn't want it any higher than that really. To remove that filter driver try browsing to the following key in regedit: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}\ Look in the upper/lowerfilters values, you should see it listed. Simply delete it and then reboot.

lol I'd hurl some abuse at you for being so stupid but you're just not worth it.

If you look at the top blue line you'll see that your CPU %usage was at 100% whenever the device buffer goes mad. So the two are linked, you just need to find out what's causing it. Next time it does it, bring up task manager and find which process is using all the CPU time. As for filter drivers, you should remove this one: siremfil.sys It's known to cause problems.

As mentioned in a previous post, there must be some issue with sending data to the drive then - and it's out of ImgBurn's hands. Check your filter drivers using the free tool from http://www.bustrace.com and remove any rubbish you find. You can put it's info in the clipboard and paste it on here if you like, then we'll help point out the bad ones (if there are any). You really don't need a 256MB buffer, as you've seen, normally when there are problems it's the 'software buffer -> drive' communication that suffers, not 'hdd -> software buffer'. The default values work best, that's why they're default! I have 4GB of RAM and I still only use a 20MB one (or 40MB in the newer version of ImgBurn - as yet unreleased). Again, if you can get us a DVDInfoPro screenshot of the 'ImgBurn Graph Data' it would help use to see what you're seeing. NEC drives perform WOPC as they burn so I'd expect the device buffer to drop to 0 every now and then anyway.

You know what I mean

ah I see, I guess it makes sense that the cutdown version of the enclosure has a cutdown version of the chip... no need to pay for firewire support if you're not going to use it!

It means the same thing it's always done (this is a long standing problem on this server).... you're posting some characters in a combination that's seen to be a potential security issue. It's NOTHING at all to do with the forum or the forum software. It's low level apps kicking in and stopping you from (what could be) hacking the server. Just go 'Back', amend your post and then submit it again. I've not have one of those errors in Aaaaaaaaaaaaages now, you just have to watch that you're not doing things you wouldn't normally do with the English language.

I don't think you're getting it. ImgBurn ALWAYS reads from the 'Buffer'. If the 'Device Buffer' empties, it's because the program can't send data quickly enough to the drive and so the drive empties it's own buffer (the 'Device Buffer'). That's down to your OS as a whole. The status of the 'Device Buffer' is simply queried (i.e. how full / empty it is) - this is a single command send to the drive. The drive then fills out the values (available / total) and sends it back. The drives normally only have a 2mb (or 8mb if you're lucky) internal buffer so it's not as if it lasts long. Even at 1x, that's not even 2 seconds worth (taking it that 1x is ~1.3mb/s).

Last time I checked, it too worked ok under Wine.

How did you manage to buy 6 new enclosures with an old chipset in them?! The one I got off svp the other day had a 3507 in it.

That MCC media should be 16x, your drive is only saying 4x so I'm guessing it's not supported by the firmware properly. The 8x stuff should be ok, that's been around longer.

yeah I've got the flasher and firmware somewhere. Latest flasher I have is rw_pl3507_icp_v23.zip Firmware is fw_pl3507B_d042006.zip

The device buffer is the drives internal buffer, it's not something ImgBurn uses. ImgBurn uses the data in the other buffer and send it directly to the drive, which then fills the device buffer and starts burning. If the ImgBurn buffer is full and the device one keeps messing up, there's not a setting in ImgBurn that will help you. If you could get us an IBG file or screenshot of the graph data displayed in DVDInfoPro, we might be able to spot weird things.

You're on the initial firmware, you should probably go for a new one (SB04). http://forum.rpc1.org/dl_firmware.php?download_id=2265 As Shamus said, the media you're using is pretty awful (no matter what you think your experiences with it have been) and you'd do well to change it for something better. Drives slow down when they can't burn and they slow down when they can't read. Seems to me that you're experiencing both of these issues. The updated firmware may help but ultimately, you need to ditch the Riteks.

Doesn't look like CloneDVD was used at all.... otherwsie why would the image mention mkisofs for the 'implementation identifier' ? Unless of course you're talking about a fake CloneDVD and not the Elby/Slysoft one?

What you really mean is that you need a tool to convert your files into a DVD Video disc - this is the bit I was saying ImgBurn doesn't do - hence why it's not working for you. Nero has tools to convert things, Nero Recode, Nero Vision etc.

Well yeah clearly the data on the disc is the same so when you view the content, you'll get the same picture quality etc. That's NOT what we're talking about here though. We're talking about the quality of the burn - i.e. how easy it is for the drive to physically write to the discs and how easy it is for the drive (and any others) to read back from it. It's like when you cook something, you could use mega expensive ingredients or you could use the cheapest nastiest crap you could find. You'd end up with the same meal, just one would taste fantastic and the other could be used to unblock your drains. As I've said before, your talk of burning Vobs Vs burning Images is Null and Void. The exact same commands are sent to the drive no matter what you're burning.

Never heard of it. Why would you even begin to look at a drive you don't already know about? Personally, I'd stick with what you know works. Plextor, NEC, Pioneer, BenQ, LiteOn, LG etc etc. I prefer to keep away from the rebranded drives. Seems pointless getting one of those to me, you just have to wait for them to catch up (firmware wise) all the time.

I bet if you'd burnt that same disc using the ISO it would have worked. The source has NOTHING to do with it - or at least not in ImgBurn it doesn't. With shite media you just have less chance of it working, that doesn't mean it won't ever work. Lets say you have a 30% chance of success with Ritek and 30% chance of failure with Verbatim. I know which one I'd rather go for. (Those numbers are of course made up though, it's more like 50/50 for Ritek and 98/2 for Verbatim)

Considering that the image burning code is the core of the program and the file burning code simply wraps around it, your theory just flew right out the window. This might sound a bit arrogant but I've been doing this long enough now to know what's a problem with the software and what isn't. Once the command has been sent to the drive, it has control over the success / failure of that command. Either it manages to write the data to the disc or it doesn't - the software doesn't even come into it. ImgBurn simply reports back any error the drive returns... and this is what your drive returned: 'Write Error' might look like it's come from ImgBurn but that's really just an 'English' representation of a couple of numbers the drive returns in something known as 'Sense Area' data (ASC and ASCQ). You can read the MMC specs if you'd like to know more - http://www.t10.org Good burns are achieved by having a decent combination of hardware, firmware and media. i.e. if any 1 of those is out of sync with the other 2, you'll get errors - and that's what you're experiencing. It's very rare to get an error when you use a good drive (which the pioneer is), up-to-date firmware (1.23 isn't up-to-date) and decent media (which verbatim is). No, none of us work for Verbatim. The reason we recommend it is because it works! If I told everyone to use Ritek DL discs I'd have a lot of angry users - the stuff is just shite compared to Verbatim DL media! That's it, end of story.

Please don't hijack other peoples threads, it's rude. Update your firmware, ditch the Ritek discs and buy Verbatims instead.

ImgBurn should work fine for the booktype stuff on LiteOn / Sony drives.... it certainly works fine on all the ones I have. DVDInfoPro's LiteOn code hasn't been updated in ages and so really only supports the first generation of their booktype code - whereas I've personally tried ImgBurn on their new 18x burners and know it works fine.
