Your problem is that you only have one tuner. That simply means you can 
only watch one TV program VOD cannot automagically change the properties 
of your hardware.

You cannot connect to the card twice at the same time. The old 
connection should be closed and a new one opened. A better solution 
would be to use broadcast or multicast the stream to your network 
segment. Then you can watch the stream (one stream) from every pc in 
your network.
