Thanks for the reply. I was watching those mkv's on my htpc already just wasn't as impressed after I saw the ps3 output. I went out today and upgraded to a Radeon 6870 as it is HDMI 1.4 and it was replacing a 4670. It wasn't as easy to get working as my last 4670, I will have to fiddle with it some more. I figured maybe i needed HDMI 1.4 as i want to use Bluray .iso's. I already bought tmt 5 and the latest power DVD, I also have a 10tb unraid server, so space isn't an issue..
Any other comments or suggestions?
