Black Hole

The PI/PO graphic above was made at MAX speed (5x CAV = 5-12 Linear) with an old version of Nero DVD Speed. I downloaded the last version 4.7.7.15 and made a test at 1X speed and PI errors were below 8 all the time. The disc was perfect, but the structure was NOT. I have burned again with RecordNow 7.3 and it worked. However, the layer break was changed by the program itself, at 55/45 percentage level (VOB ID 1, Cell ID 11) and the IFO file changed without user intervention. If the original disc has a different layer break, and the same is suggested by ImgBurn, why didn't it work as expected with 70/30 ? The problem is not the disk being jerky at a certain point, or freezing in the layer jump. I think that not being read at all could be a problem in ImgBurn algorithms. Two high quality discs cannot fail in such a way, since the first was burning the ISO created by DVD Decrypter and the second one was building the files from the VIDEO_TS directory.

I don't know if these are good or not. I have only Nero 6.6: General Information Drive: BENQ DVD LS DW1655 Firmware: BCIB Disc: DVD+R DL (MKM 001) Selected speed: 8 X PI errors Maximum: 713 Average: 180.21 Total: 3752580 PI failures Maximum: 3 Average: 0.15 Total: 1030 PO failures: 0 Jitter Maximum: 12.5 % Average: 9.69 % Scanning Statistics Elapsed time: 11:10 Number of samples: 22395 Average scanning interval: 8.02 ECC Glitches removed: 0 By the way, I don't understand very well why ImgBurn shows four 50/50 break points with so much different time values. Why do you need to pad so many sectors in the first case? AFAIK is to have an equally layer size, but ImgBurn only seems to pad the first layer when it's smaller than the second layer. Why doesn't ImgBurn pad the second layer if that one is the smaller one? Should it? Thanks.

Well, the original disc had that structure, and ImgBurn showed it with blue "Very Good" star. That's why I was asking you if it was out of specification for DVD Video recording standard ... Do you want to know something more strange? I'm having a lot of problems to read those 2 discs in my MSI 8216S PC IDE DVD reader and they are not recognized at all in both a common Pioneer DVD-115 reader and a Pioneer DVR-107D burner. Obviously there's something fishy in here, as I haven't had problems with 25 other DVD+R DL before. If I can provide you more info, don't hesitate to ask.

Hello, I've been a long time user of Decrypter and ImgBurn and this is the very first time I have a problem. I have successfully burned many Dual Layer discs in the past, but this one is failing. I got an ISO of a DL DVD which is less than 5.5 GB long. I burned the ISO without any problem but then the disc didn't work in my 2 home DVD players (CyberHome ADL-528 and Best Buy Easy Home DVD) which accept any other DVD+R DL burnt in the past. I extracted the contents from the ISO to another directory. I checked the MD5 sums against the ones from the DVD and were the same. So I tried to burn another disc using the "Build" option within ImgBurn, just in case it got mad with the ISO file provided before: I 13:44:23 ImgBurn Version 2.3.2.0 started!

But the disc refuses to be recognized in the DVD players, as it starts to click several times before the "Bad Disc" message appears on my TV screen. There is something "peculiar" regarding to this disc. The layer break is at 70/30 % point, so a full first layer is burnt and only a fraction of the second layer, so you can clearly see the different colours of the disc dye. Could it be the problem? Is out of specification? Can the layers be so different in size? Should ImgBurn have padded the second layer in full? Reauthoring programs such as DVD Remake Pro don't detect any errors in DVD structure.
