thollian Posted July 23, 2007 Posted July 23, 2007 Not sure how to read this, nor if this is the write place to post this, sorry if it isn't, but is this a good or bad burn? thanks
cornholio7 Posted July 23, 2007 Posted July 23, 2007 the spike at around 1.5gb doesn't look too good. its a shame you couldn't measure jitter, it would give a more accurate result
thollian Posted July 23, 2007 Author Posted July 23, 2007 the spike at around 1.5gb doesn't look too good. its a shame you couldn't measure jitter, it would give a more accurate result so does that indicate a bad burn? or possibilty the disc will not work at a future date?
thollian Posted July 23, 2007 Author Posted July 23, 2007 here is another screenshot using my burner to test, just wondering how well the burner is burning since it is a year old....
blutach Posted July 23, 2007 Posted July 23, 2007 The disk is certainly out of ECMA spec. I'd re-burn. Anything happen to the data flow while you were burning? Is there a log? Regards
thollian Posted July 23, 2007 Author Posted July 23, 2007 The disk is certainly out of ECMA spec. I'd re-burn. Anything happen to the data flow while you were burning? Is there a log? Regards there were no errors durig the burn, and the disc plays fine though? so how can the disc be out of ECMA specs, when it plays fine?
blutach Posted July 23, 2007 Posted July 23, 2007 Playing OK and being outa spec are 2 different things. A few poor sectors you won't notice. The ECMA standard are specifications as to what determines a good burn as definied in ECMA 349 (section 6, chapter 32.2). 1. No consecutive set of 8 blocks (sectors) should have a total of more than 280 PIEs. Clearly, your disk does not comply and should not have got a "96" quality (in fact, it looks like it does not comply at about 40-50% of the points on the disk's surface) 2. No block should have more than 4 PIFs. Many sectors on your disk do not comply with the standard. 3. Of course any single POF (better known as a CRC error) makes the disk fucked anyway. Regards
thollian Posted July 23, 2007 Author Posted July 23, 2007 (edited) so with the disc being out of spec, does this imply that 1) the disc may/may not play correctly in a future date? 2) does this mean my burner is bad and doesn't burn good anymore? or really if the disc, does not meet the spec, how does this affect me? short/long term? thanks for your help.

blutach Posted July 23, 2007 Posted July 23, 2007 1. No. No-one has such a crystal ball. Some players are more forgiving than others anyway. 2. Not sure just on a single burn. Check out some other ones that you do. Your blanks should be OK. Usually, you see poor stats on the outside (end) of the disk. Do some more tests, perhaps also in a different burner. Maybe burn at slower speed as a test (8x). Is there a log???? Regards

blutach Posted July 23, 2007 Posted July 23, 2007 Tried cleaning your drive? And, it's worse with PIFs (which have degraded your "score"), but not PIEs (which look fine). Admittedly, the PIFs are more important, IMHO, anyway. Try burning at 8x. Regards
thollian Posted July 23, 2007 Author Posted July 23, 2007 (edited) no, I haven't cleaned the drive, I will do that. so the log looks ok? I just burned a dvd at 8x, and these were the results: looks like it has done better burning at 8x rather than 4x....I always thought slower the burn, beter results.... first image @ 8x second @ 16x Edited July 23, 2007 by thollian
blutach Posted July 23, 2007 Posted July 23, 2007 Ther only graph that looks "normal" is your last one and even that is outa spec (but at least its bad at the end). Do clean the drive and see what happens. Regards

thollian Posted July 23, 2007 Author Posted July 23, 2007 this disc was burned when i first got this drive, how does this compare to the more recent ones?
LIGHTNING UK! Posted July 23, 2007 Posted July 23, 2007 It pretty easy to see the blue coloured 'PI Error' graph is much lower in the first burn you did. You got a max of 20 in that one, rather than 300 in the other scans! You should stick to doing the scanning in the LiteOn drive though. You can't really compare 2 different drives - even if they're the same make/model!
thollian Posted July 23, 2007 Author Posted July 23, 2007 (edited) so what exactly do these graphs/numbers mean? I mean if I can read the data fine, how does this really effect the disc and the data on the disc? especially since I can read the same disc on the same drive and get different numbers each time, even though they are around the same.... also, is C1 one good, and C2 bad? Edited July 23, 2007 by thollian
cornholio7 Posted July 23, 2007 Posted July 23, 2007 C1 is the top (blue) part of the graph C2 is the bottom (green) part. we tend to use dvdinfopro on this forum, theres an explanation here http://forum.imgburn.com/index.php?showtopic=2168 maybe comparing your pie and pif totals with the one in the link may help
thollian Posted July 23, 2007 Author Posted July 23, 2007 ok, I bought a new dvd cleaner, and burned something new, and here are the results, looks like a huge improvement, if I am reading this correctly?
thollian Posted July 23, 2007 Author Posted July 23, 2007 here is a screenshot taken with DVDInfoPro....
thollian Posted July 23, 2007 Author Posted July 23, 2007 looks a lot better than posts 1,4 and 12 would you say its acceptable burn? or the burner is showing signs of wear and tear/age?
cornholio7 Posted July 23, 2007 Posted July 23, 2007 the last scan is certainly acceptable. jitter can affect the quality result dramatically but the scan looks good
thollian Posted July 23, 2007 Author Posted July 23, 2007 the last scan is certainly acceptable. jitter can affect the quality result dramatically but the scan looks good thanks for all your help, one last question, what numbers are consider acceptable, and what is not consider acceptable?
