I am new to the HTPC scene. I have been doing some research, but I have a questions about a few components that I already have. I have a Toshiba 51H83 RPTV. A few components that I would like to know if I could use in my HTPC are my ATI Radeon DDR 128 MB display adapter and my Creative Lab SB Audigy card. I will be connecting my sound to a Sony STR-DE945 receiver. I have Bose Acoustimass 6 Series II 5.1 surround speakers. PLEASE HELP.
