I too had problem in configuring the SAA7130 based card under Linux.
First i was using PCLinuxOS which is based on mandriva distribution but now using Ubuntu.
It took me almost 1 year to figure it out how to configure. so i documented it here
http://jobinau.googlepages.com/saa71...cardunderlinux thinking that it will be useful for some of you if you are stuck.
It was too hard to get the audio working. but nowadays i am watching the TV in my Linux box.
It should work with any distribution because the driver SAA7130 is shipped with all new kernels
