Optimummind -
www.vcdhelp.com - all your questions will be answered there :-) Also,
www.doom9.org has plenty of information on video capture.
I think that your question wasn't answered for a number of reasons:
1. There are a lot of steps involved and it requires a fairly long answer which is answered on various websites in their guides.
2. This forum is intended for ATI video capture hardware, rather than hauppauge, so what applies with ATI may not with the WinTV.
Check out those websites - vcdhelp has excellent step by step guides to walk you through the process.
