  1. Thanks for the info. Didn't know layer break didn't apply to BD discs. The player is Samsung BD-H6500. The verify was off when I burned the disc but afterwards I ran it through BDInfo to scan the bitrate and it finished reading the whole disc without problem,. The disc plays fine to the end except for that particular spot. I will do more tests and see what happens.
  2. If the size of the content is less than the full capacity of a BD-R DL, how does ImgBurn determine how much to put on each layer? In the Write settings there is an option to select layer break with two choices: calculate optimal and user entered size for layer 0. I burned a BD-R DL of an iso about 40GB and the layer break option was at optimal. It appears that ImgBurn used the layer 0 to the full before going to the second layer. When payed the movie has a considerable pause, about 20 seconds, at a point in the movie which I suspect is at the layer break. It always happens at the exact same point in the movie, and then plays fine to the end. Well, it could be that this particular disc had some bad sectors, but I thought I would ask about the layer break. If the content size is less than the full capacity, is it advisable to set the layer break manually, say, half on each layer? BTW, I use Verbatim discs exclusively.
  3. I ran memtest86 for a couple of passes. No problem was found. After that I burned 7 BD-R discs with no miscompare warnings. But on the lastest burn I again got miscompare. Only one on the whole disc. The log of that session follows. After the burn I calculated md5 for the file in question on both the burned disc and on the local hard drive. They were identical. Should I just ignore miscompares altogether? ----------------------------------------------------------- I 19:06:57 ImgBurn Version 2.5.5.0 started!

  4. Curious that you mentioned memory issue. Come to think of it the only change I made to my system recently was to add additional memory. Before that I had never gotten miscompare when verifying in over 300 burns. Sorry, didn't save the log. Next time it happens I will post the full log.
  5. I am getting miscompare warnings when verifying after the burn. Example: W 00:41:39 Miscompare at LBA: 833640, Offset: 1102, File: \BDMV\STREAM\00000.m2ts W 00:41:39 Device: 0x4C W 00:41:39 Image File: 0x6C W 00:41:39 Total Errors in Sector: 1 This is from a burn of a BD movie to a Verbatim BD-R. There were 8 of these. And in each one the total errors in sector was 1. Does that mean a total of 8 bytes on the disc are different than the original file? My experience is that if something goes wrong during the burn - bad disc, bad burn, whatever - then the entire sector, and most likely several sectors, become corrupt and unreadable. But in this case the sector is readable but one byte is different. How does this happen? The program tells the drive to burn A and the drive burns B?
  6. I have a Pioneer 110 DVD+/-RW DL, and use FujiFilm DVD+RW 4X discs. ImgBurn writes and verifies OK, and the burned disc plays fine on the computer and stand alone player. The problem is that when I want to rewrite the same disc I have to do a full erase each time. ImgBurn doesn't recognize the disc as formatted.
  7. I have used ImgBurn to burn disc images of DL DVDs. Images are usually created with DVD Decrypter or PcgEdit. I use Pioneer 110 and Verbatim +R DL discs. I never had any problems. All burned discs played flawlessly on my standalone player. I have verify option on and all burned discs verified without problem. I usually don't pay attention to the log window if the burn and verify complete successfully. However, in the last couple of burns I happened to notice some lines in the log which looked like warnings; they had yellow exclam icons. Sorry, I didn't write down the exact words, but their gist were like this: Optimal Data Zone Capacity: Copied from original disc... Setting L0 Data Zone Capacity... Data Zone Capacity Miscompare...wanted X got Y... Y was about 12 sectors larger than X. I take it that X was the layer break read from the MDS file. Despite these warnings the burns completed and verified successfully, and the burned discs play fine in my player, even the layer break transitions. So, my question is what do these warnings mean? What happened to the layer break? It seems that the layer break in the burned disc is at a different point from the original disc. I thought layer break could only be at a cell boundry, and there is no other cell in IFO which is about 12 sectors from the original layer break cell. Even though as I mentioned the discs play seemingly fine, I wonder if there are some subtle anomalies in their structure. Do I need to redo the burns?
