Hi

I don't know much about Xv or DGA but it seems to me that the main
problem is that xawtv cannot locate grabber device. Is it detected by
driver? Search for some info in kernel messages (dmesg command or logs).
If it's detected then you should pass location of device to xavtv with
`-c' option. 

If You need more help then please provide some more info about TV card,
driver, distro.

Note I can help You If You have Bt8x8 chipset as I have some experience
such card. If You do own such card then take look at
`http://bttv-v4l2.sourceforge.net/' and `http://bytesex.org/v4l/'. Maybe
You'll find some more info there.

Good luck,

- Jacek
