Hmm, reading the slashdot thread about TNG on TNN... makes me think I should write a star trek unsquasher. The theory is easy. Just discard the bottom 60 rows, feed the rest to Xvideo, and have the graphics card do the scaling.
I'll put it on my to-do list. I don't really watch the show much, but I'd get to learn v4l AND Xvideo in one fell swoop, and those are things I really need to know.
No programming this weekend :)
