I can connect my PC to the TV via a video/sound cable and a special SCART adapter. The cable plugs into the video card on the PC, and the SCART adapter plugs into the TV.
The adapter has a switch for data flow direction. If I am recording, I put the switch on IN, else it goes on OUT.
I also have PowerDVD, but that is just a DVD player. If you have a laptop, they normally all have the function to switch output, so you should have no problem sending the data to the TV.
Do you have a SCART adapter with your cable ?
