I had one of those a while back. I replaced it with a new one that cost
me something like 30 GBP (about 59 USD, or 40 Euros) and the new one
handles a wide variety of formats, including reading DVD+RW, and also
does Dolby 7.1 audio even though I don't need that feature. The only
possible down side to it is that it's a region 2 only player, whereas
the old player was region free.

It all depends on the source file. If your source has a frame rate of
29.97 fps, I'd probably use:
ffmpeg -i source.avi -target ntsc-dvd -sameq output.mpg
If it's 25 fps, I'd use:
ffmpeg -i source.avi -target pal-dvd -sameq output.mpg
If the frame rate wasn't either of those target rates, I'm not sure
which one I'd use. Most likely I would create samples using both pal-dvd
and ntsc-dvd as the targets, and see which one looked better.
If the source had frame rates of double, or half, the PAL or NTSC rates,
e.g. 12.5, 14.98, 50 or 59.94 fps, I'd use the pal-dvd or ntsc-dvd
Also, to try and minimise degradation due to another transcoding
session, I always use -sameq. That uses the same video quality for the
output as for the input.
Beyond the above, I couldn't say as I rarely transcode from AVI to MPEG.
My player handles xvids, so I don't actually need to do so.

Yeah that's a problem. Also you might have noticed that avi is sort of a
generic term. There's Xvid avi and DivX avi for example.
DivX is supposed to be sort of the leader of the pack here and Comcast
is gonna roll out a 50MB/s connection in their area. They intend to
serve up movies in DivX format.
There is the latest iteration of DivX that is supposed to include
chapters, subtitles, and so on (check the spec's online for precise
details). One down thing about my player is that is supports the
previous standard but the new format is backward compatible - You just
won't be able to use the latest DivX features.

Yeah I really want to expand my video work under Linux. For one thing a
Windows box is too sensitive. If you try to run a another app it might
(and has for me) cause the encoding that's going on to have a "bad spot"
in the video. It's the same old problem that M$ OS's have had for years
- Each app likes to hog system resources.
This weekend looks good for me to do some new stuff with Suse and video.
I pretty much have it set up nice now, lots of fonts, etc. I just wish
there was an easy way to change Gnomes' colors to what I'd like to have.
Hmmm, dvdstyler, eh. That one has got to be added :-)
