TV Tuner cards?

[Alex]

Hi,
I'm interested in a TV tuner card that I can connect to my roof
antenna with a RG6 coax, and wondered if anyone had any suggestions?
I've used the Happauge cards in the past, but that was quite some time
ago. I've found the linuxtv.org page, and although they have a list of
available TV tuners, they don't really give any impression on which
have the best features, etc.

I'd probably also like to set up MythTV at some point.

Anyone have any suggestions?

Thanks,
Alex
