As i said i haven't had any problems with my tt s2-3200 and multiproto 
driver.
I believe that "budget" cards like that one are easier to support 
because their design is basic.

some usb dvb-t adapters are supported but never tested that so i can't 
tell for sure.
i need to get a dvb-t device myself but it'll be a pci one..

There's no GPU hardware acceleration currently on linux, as far as i 
known, besides xvmc for MPEG2 on nvidia chipsets if i'm correct..
So you'll have to rely only on your CPU for decoding h264 and that can 
be quite tricky with 1080i..

As Igor pointed out there's an existing project to bring coreavc support 
to 64 bit linux, but i couldn't get it to work so far and have no idea 
how stable it actually is..
Having something that "works" is very different from having something 
that works but will crash or freeze your app every few channel zap..
But again i'm not telling it's not working as i couldn't get it to work 
on my setup yet..

Good luck.
