There was some preliminary work in http://linuxtv.org/hg/~pascoe/xc-test/ that got DVB-T working with this card in 2.6.24. Analog TV, composite, svideo, remote controls, etc didn't work (or at least I was told they wouldn't work and I never tried them). Is that what you mean by 'quite broken'? I'm not familiar enough with the linuxtv codebase to make judgements of what you mean for myself, but am willing to learn. All I've really done is applied patches that Chris supplied me. > Fundamental portions of the cx88 driver need to be redone, and for > your card, that will mean going back to Windows to see what the > vendor's driver is doing with GPIO in response to different inputs, > as well as some experimentation.

Done, at least some preliminary (i.e. non-exhaustive) results.
