Hi, Help -- I borrowed a KWorld KW-TV878RF-PRO (which uses the 878A chip) and I am trying to set it up. It works fine under Windows, but I can't get the tuner to work under Mandrake 9.1 (running 2.4.21 -- not sure what version of bttv is included, how do you check?). The composite video-in works fine (using a VCR as the source), but I get snow with the tuner (using xawtv). I plugged in another tuner (complete video card actually, ATI AIW 8500DV), and I have no trouble with it's tuner. Any pointers? ...thnx, ...dave ps The quality of the tuner under Windows was lacking compared to my ATI tuner -- are these cards generally not that great, or is it the tv program (used different programs under Windows)? I'm pretty spoiled with the ATI tuner, it looks really good on my monitor. :-)
