remote TV viewing?

[Torfinn Ingolfsen]

I have a multimedia machine, which has a TV tuner card, and is connected
to the (local, in-house) network.
After setting the appropriate access controls, I can do things like:

DISPLAY=my.workstation:0.0 xawtv

and have a TV display on my workstation, which is another room. Great
when I just need a quick view on the TV, for weather reports, news, etc.

But, how do I get the sound transported to my workstation?

BTW, is there a better way to do this? (remote TV viewing)
I tried with vnc (tightvnc), but couldn't get a picture from xawtv
(there were complaints about the "RENDER" extension missing, or the
"XVideo" extension, depending onm which program I tried).
Installing a TV card in my workstation isn't an option at the moment.
