I've got the Leadtek card; it has a CX23882 chip. I run 2.6 and am
mildly familar with the driver.. I think my patch was the first one to
fix the tuner (typo in the tuner defs) and added it to the card
database. I haven't touched it much since, though. They've got the wrong
decimation values for NTSC but I didn't have my TV books handy and they
didn't believe me. (The VBI data lines are _outside_ the viewable area;
that's why there's a separate capture unit for them. address@hidden)

(Who doesn't think that watching the closed captioning flicker in the
window adds anything useful.)
