Pretty sure Brian was talking about trying to use an ATI All-in-Wonder
for capture. This won't work because the AIW isn't a digital capture
device or a hardware encoder or even a frame grabber. I tend to think
of it as a "black-hole TV card"--AFAIU, it's designed to tune a channel
and scale and display the video into a black hole defined on the screen
(meaning it's meant for live, non-recorded (non-pausable, -rewindable)
TV. It /can/ be used as a capture card of sorts by reading the frames
out of video card(?) memory (thus making it a /very/ convoluted design
for a frame grabber), but that's really using the wrong tool for the job.
See http://gatos.sourceforge.net/

Note, also, that the problem is *not* that MythTV doesn't support ATI
AIW, but that V4L/DVB doesn't (and can't) support it (cleanly). And,
for those who aren't keeping up with FOSS development (and who may not
recognize the importance of version number information on the Gatos
page, please check the date on the bottom of the pages.)
