    What's the running time of the video? Filesize means nothing, when talking about an unknown compressed avi.

    It means how long it is, on WMP or any other player you should see it easily (e.g. 1h 40' 23").
    This because (S)VCD = mpegs and mpeg size depends only on its type and duration. VCD = MPEG-1 (CBR) = 10 MB x minute (about 800 MB for a 80' movie. You can fit exactly 807 MB of cue/bin in a 80' CD-R, and 'authoring' a VCD [MPG
    -> [bold].bin[/bold] + .cue] takes about 10 MB - a 80' CD-R has room for 2352*360,000 bytes = 846,720,000 bytes (807 MB) of 'RAW image'), which corresponds to a 1150 kbps bitrate; SVCD = MPEG-2 which is VBR, but it's better keep a bitrate so that size = minimum 800 MB for 55' length (looking at TMPGenc's wizard...), which corresponds to about a 1800 kbps bitrate (if the movie is shorter (or the movie is split on many CDs), you can keep a bitrate higher so that size = 830 MB. Use FitCD and look at the guide http://www.afterdawn.com/guides/archive/dvd2svcd_with_tmpgenc.cfm (FitCD part) , and , in general, to the whole guide (except the DVD / VOB --> MPG ripping/converting part, since converting an AVI is easier), for this.
    Just a thing: make a check that the audio used in that AVI ia CBR and not VBR (read the FAQ http://forums.afterdawn.com/thread_view.cfm/196299 , expecially http://forums.afterdawn.com/thread_view.cfm/129217 )

    No, it won't interfere, it is necessary!
    We still need to know how long it is. Hours and minutes please.
