avi to dvd

[natty]

I have a .avi movie which i used winavi to convert to dvd ie: audio_ts and video_ts containing vob and ifo files the .avi movie is 700mb but after i had converted it to dvd its now 2.91gb why is this

Hmm, I realy don't understand your complain - it is too big, or it is too small?

Because a lot of (presumably) downloaded clips use XviD or DivX, which can achieve much better compression then MPEG-2 at the same bitrates (in general terms you normally need to use roughly 3-4x the bitrate of the AVI to retain the same quality in MPEG-2). So therefore I'd expect the MPEG-2 file to be roughly 3-4 times bigger than the AVI in this case.

Hi thanks for your reply i amd looking at your guides its very handy thanks its just that i was told if the .avi movies i have are about 700mb i should be able to put about 5 on a dvd but i cant as i have to convert to dvd so my home dvd player see`s them

If they're about 700MB then you can put 6 on a Data DVD (which will play fine on your PC) but if you want them playable on a settop player then you need either a DivX/XviD-capable player or you have to go the conversion route.
