    1) convert any movie into a DVD Movie (avoid choosing a bitrate so that each movie fills 100% of the DVD; choose the bitrate according to th minutes of duration of the movie and considering that 155' movie = 1 4.7 GB DVD-R, at normal bitrate (e.g. a 15' movie = 10% 4.7 GB DVD-R = 0.47 GB) (avoid selecting an option like 'automatic fix the bitrate' in your encoder, or it will force every piece to fill 100% .

    2) author a DVD containing multiple movies, like you inserted many clips on a VCD. Sorry I don't know the applications, but I think DVD Lab can do it. Surely Nero cannot, because it will try to make 1 movie fit the whole DVD (by default, because it automatically encodes the AVI this way, when you load it. Probably it makes the same with an already encoded movie).

    You can reduce your 30 min divx to any size mpg you want...but below about 1 gig, it's hardly watchable, and at 500 meg, it'll be nothing but large green blocks.
