This card works extremely well in linux, at this time it isn't supported directly out of the kernel but simply building the drivers from the v4l-dvb CVS was all it took and that wasn't at all difficult to do, they have great instructions in their wiki.

Simply a matter of loading the module then you can generate your channels.conf. This is done pretty easily with the tools in a package on their site called linuxtv-dvb-apps, I used version 1.1.0. I couldn't get tvtime to work with the card, apparently it only supports traditional v4l devices, not DVB cards but if you just copy the channels.conf to ~/.xine you can watch TV with Xine and the channels will list themselves in the playlist.
