Hey all Hope someone can help with this, I upgraded my HTPC today by changing the graphics card to a sapphire ati 4870 VAPOR model with hdmi out and installed an lg blu/hd-dvd reader however now tmt won't play anything.. I uninstalled the old graphics drivers for my ati x1950 before installing the new card. And I'm using the ati 9.4 drivers for the new card. I have not installed any of the software that came with the blu/hd-dvd reader. And have tried uninstalling and reinstalling tmt but it makes no difference. I am running win vista home edition 64bit, service pack 2. I would appreciate any advice anyone has..
