How do you set dvd::rip to end up with a 16:9 aspect avi file taking up

It's really pretty unusual to make avis that large. Are you using XviD?
There is a maximum quality you can achieve with each codec. With 4.7 GB
target size, you could as well use MPEG2. Or try h264 (wild guess, but
this is the codec with the best quality in linuxland atm).
Thanks Thomas,
Yes, I am using xvid which is using the h263 quantization method by default.
Should I choose mpeg instead of h263?
Without going into too much detail, that's something different. XviD is
a dialect of MPEG-4. H.264 is a different, newer standard. MPEG-2 is yet
another standard used on DVD's (=ooold ;-)). Hardware players can do
MPEG-2, some can do DivX/some parts of MPEG-4 and XviD if you are
careful not to enable the advanced coding options. I know of none doing
H.264.
Then there are containers: mp2 (only mpeg2), mp4 (only mpeg4), avi
(anything, but limited), ogg (anything), mkv (anything and more, not in
DVD::Rip last time I checked).
If you don't care about HW players, you might find ogg a better
container format then avi (uses less space, audio/video don't get out of
sync as easily, multiple Audio tracks/subtitels supported...).
Hm, or stay with avi, I don't want to confuse you. All of this is a bit
of voodoo. :)
xvid is the default codec selection. I can't find h264 in the transcode
options.
ffmpeg does, it's a library providing different codecs.

T.
