As already indicated, it can be easily done using a cheap capture device. I believe you can also get one of these with a built-in satellite receiver but have never used one.
There are drawbacks however:
Wires everywhere
"Nuisance" to set up
Out of synch sound
Poor viewing angles and contrast on laptop monitor
High current consumption compared to small LCD TV
We've tried it but now use a dedicated TV and satellite receiver, it's much easier and better to watch.
