Pixelation near the end of movie copies

    I'm seeing a trend of pixelation near the end of movie copies. Most of the movie plays well until the last 10%, then periods of pixelation occur regularly, and maybe 50% of the last minutes are broken up. I'm curious what is different about the end of clone job and why errors are not evenly distributed. I'm assuming it is issues with the transcoding.

    I'm using the latest versions AnyDVD and Clone DVD. Reading the master from one Pioneer drive and burning on a Pioneer 212D, with lastest Pioneer firmware. I'm currently using Verbatim DVD-R 8x media (DVD-5). I'm using all CloneDVD defaults, burning at Maximum speed. CloneDVD always tells me that the copy completed with no errors.

    I read a previous posting which advised to set the size to 4300 and reduce the burn speed. I haven't tried that. I also saw a comment not to use DVD-R media, just +R. I'm trying to understand why these things make a difference, and how to improve my copies.

    Don't. Do not burn at max. Try a 6x or even a 4x burn speed.

    1. Update your burner's firmware (if available)

    2. Use good quality media (Memorex, Ritek, Princo, Fuji, TDK from Costco, and Maxell that are not made in Japan are not good quality media). Are you using inferior blank media? If you're not using Taiyo Yuden (not valueline), Verbatim, or Maxell Broadcast Quality, then chances are the answer is yes.
    If you use poor quality blank media, then you should expect problems.

    For +R DL blank media, use Verbatim made in Singapore or MAM-A 8x +R DL.

    3. Try lowering your burn speed (not below 4x; if you have a 16x burner and 16x rated media try writing to it at 12x instead of 16x; an 8x burn speed on 16x rated media wouldn't be a bad idea either)

    4. If you're using +R, +RW, or +R DL media, change the booktype to "dvd-rom"

    5. Avoid sticker labels (they tend to cause problems)

    6. Try setting a custom size of 4300 in Clonedvd (but if you're using good media, you shouldn't have to) if you're using regular single layer dvd-5 (4.7GB) discs.

    7. Download Nero cd-dvd speed. It's a free program. Select the tab labeled "scandisc". Insert the problematic backup disc, select the appropriate drive letter, and click "start". If Nero cd-dvd speed reports read errors, your backup is bad (which is the most likely case), your optical drive may be slowly dying, or your optical drive simply doesn't like the disc (or your choice of blank media)--even if the disc looks fine.

    Bad burn quality is notorious around the end of discs (see step 6)
    and also at layer breaks when using low quality DL media (use Verbatim +R DL media made in Singapore or MAM-A 8x +R DL, and change the booktype to "dvd-rom")

    Also, check the preview screen in Clonedvd to ensure you're backing up the proper title.
