    Hi,

    When I am backing up my dvds I use dvd shrink or cloneDVD2. When I put the dvd player dvd shrink and clone2DVD automatically compresses to dvd to 60% or something.

    I just use virtual dub once the file is an mpeg and use the bitrate settings
    1200 for video and 192 for audio. Using Xvid and MP3.

    My question is
    If I rip the DVD without any compression using DVD shrink, will the quality of the AVI I produce be any different to one that has been produced from a source mpeg that has been automatically compressed by DVD shrink?
    Are you going to lose quality on your output AVI if you let DVD shrink automatically compress the MPEG file?

    Yes and yes. Although the quality difference mightn't be enough to notice. It depends how much DVD Shrink has compressed the video. When shrinking a DVD with DVD Shrink it re-encodes the video, so by definition you'll lose quality. In effect, you're re-encoding the video twice.

    DVD Shrink has a setting for "target DVD size". I usually set it to something silly like 10000MB so when I use DVD Shrink to re-author a DVD for encoding it will never attempt to re-encode the video. If I also want to create a DVD I get DVD Shrink to make two backup copies to my hard drive. One without compression for encoding and a second with compression for burning to DVD.

    By the way, if you have a player capable of playing MKV or MP4 files, encoding using the x264 encoder is a better option than Xvid/AVI these days. At least I think so as x264 retains more detail.
