I meant to ask about this since I have no idea what it is, I thought it
would be used for receiving over-the-air TV signals. Are you saying they
have input jacks that would work with old computers that had TV output
connections?
Often enough, yes. You just need to look for the appropriate ports; some of the REALLY
cheap ones only have a tuner and nothing else. I really liked the AVI TV Wonder that I
have (CX2388x-based, red PCB); it had a little purple breakout box with the composite,
S-Video and audio connections so that everything else could fit on the card bracket.
For Linux, my best luck has been with bt848/878 (almost the same chip) followed by CX2388x
(the next step up after Conexant bought Brooktree; there are newer chips in the series
that support e.g. PCI Express, but I don't know their level of support under Linux).
There are a handful of Philips chips supported, but I've never tried them.
The Windows viewing apps that come with the cards are almost universally terrible, but a
good third-party one I've used is DScaler (it's been a while since I've fooled
around with it, though, and they were going through a major project renovation, so it
could be either better or worse by now).
For Linux, I always preferred fbtv, but most people don't like fooling around with the
framebuffer layer any more than they have to. I really liked the ability the framebuffer
layer gave me to create custom graphics modes with weird sizes and fixed frequencies that
optimized the experience; alas, none of that is likely to work well without an analog
monitor anymore. I also liked being able to just start the viewer without having to start
X. I don't know what the general favorite is for operating it under X; when I was
using it, it was xawtv. I imagine that MythTV probably has a Video4Linux backend?
