Hi All, Just got this card and installed it all absolutely fine. Audio coming out of it ok and sounds good. I wasnt sure if i had to install the TMT that bundles with it though so i first tried to play a BluRay from my Corel WinDVD 9. That loads ok but the picture stutters like mad, and the screen has taring flicking on and off randomly - as if the picture / data isnt being sent out of my HTPC fast enough. I then tried to install TMT which also completed ok, but when trying to load it absolutely nothing happens. I can see a process in task manager appear for it (forget the name and im at work now), and its there for about a minute before it disappears. Not sure what to do next. Do you have to use the bundled TMT? Is that why my WinDVD9 didnt work? Any ideas? Thanks all, D.
