If you want an answer...try asking a question. I'll also throw out there...maybe posting in the HTPC (Home Theater Personal Computer) forum may get you a little more advice.
You could even try a "SEARCH" in that forum. I know of software discussed recently that may do exactly what you want.
I'm just saying.... Do what you like.
