I am having issues connecting my 52 inch sony xbr-6 to a HTPC; I previously had it working fine but the old PC failed and now, the only way I can get it to work is to start the pc with the video connection to the PC disconnected. After the computer boots up I can connect the tv and all is fine. The computer hangs up on the boot screen if left connected during startup. The old computer was AMD based with 2 nvidia 7600GT's in SLI; the new one is an intel based quad core with a single nvidia 8800GTS. Both machines are custom builds of my own creation. Both machines ran Windows XP. I use a DVI to HDMI adapter with a dvi cable; I have also tried an HDMI cable with an HDMI to DVI adapter with the same results. Anyone ever hear of this?
