Oh, one other thing that works great if you're transcoding or doing
anything with dvd's. Use dvdbackup rip the content to your hard drive.
Much faster encoding that way. I've been going from DVD -> h.264
using handbrake's appletv presets, and it looks great on my tv.

I tried playing with that just now, and cannot figure out a way to

If you want jpgs of each frame, I'm guessing that mplayer is what you
are
going to want. It sounds like there are two problems with the results.
- The image is squashed. This is expected, since this is how they are
stored on the DVD. This can be fixed after you get the images you
want.
I don't even know how to respond to that, so, ok. Perhaps this has
something to do with the interlacing you mention below. But if that
is the case, then I don't understand why my previous attempts didn't
produce jpg files that looked even *more* widescreen.
I'm obviously not explaining things well.
Widescreen images are stored in the same 4:3 aspect ratio as full-screen
images, just with the picture squashed horizontally. The player then
stretches the image out into a widescreen image.

This was done in film with lenses, but it basically done in software or
hardware with DVDs.
If you pull one of the images into a photo editor and stretch it
horizontally by 1.21557 times, you should get a proper picture. Again this
is expected.
