    More technically, when you try to butn mpegs with Nero, if first checks if it is in standard format (DVD: 720x480/576, 23,976/25 fps [NTSC/PAL]).
    If it 's not, Nero first encodes the movie (many hours), then burn it (few minutes).
    From your size estimate, it is clear that Nero is trying to encode your mpeg into a DVD movie copliant to your system.
    It is absurd: if you have a 352x240 mpeg (VCD NTSC) it's trying to convert it, for example, into a 720x576 (DVD PAL) one!!

    First, since Nero auto-encoding engine isn't good, make what scf_au suggests you:

    1) encode the movie in standard format.
    2) author the movie into a DVD/SVCD/VCD image.
    3) burn that image here you can use with Nero.

    As encoder, you can use VSO or TMPGenc, CCE, what you have/you like. To author (the process Standard MPG --> image) you can use much stuff DVD Lab is the only one which accepts to insert multiple (S)VCD movies in a DVD image (see http://www.afterdawn.com/guides/).
    As burner, use what you want.

    Only a suggestion: check the quality of the input movie (resolution and, if AVI, bitrate), first doing anything with it. Since [bold]garbage in = garbage out[/bold], don't try to encode a 352x288/240 mpeg (VCD) into a 720x480/576 movie (DVD). You'll only obtain crap. Leaving a (S)VCD movie as it is (or converting a low bitrate AVI into a (S)VCD movie) and then authoring it, toghether many other, into a DVD image. You'll just have , instead of making a MPEG (S)VCD movie, to resample its audio 44.1 kHz [(S)VCD] --> 48 kHz [DVD], is the best, and quickest, way..

    In the forum's title (AVI to DVD) DVD must be read as 'physical support', not as '720x480/576 movie'.

    Now that I changed my hardware to a 2.4gig pro. and 800megs of ram....Nero only takes approx. 2.5 hours for a full 4.7gig single layer burn.( encoding I mean ).......Can anyone show me how to do better do better?

    Thank you.
