I've been using one (AxC0 I think) for years until the hardware died earlier this year. I think I bought it 2006, not quite sure when exactly. I think what killed it was that it was working permanently for 1,5years, so it probably overheated somwhen in the summer. But it was working fine with analog and dvb signal.

I've never used the in-kernel module rather the v4l-dvb one for this specific card. I even did not compiled it recently.
