Hi, I'm running XP pro and installed that latest drivers for my Ultra TNT 2 cardand ran into a problem. After installing the drivers WinDVD 3 would freeze my PC completely and I could do nothing but hit the reset button. Thinking WinDVD was a problem, I then tried PowerDVD and got the same results! I updated both programs with the XP patch, I also tried them with DMA mode turned off...same thing. In the end I had to "roll-back" to previous driver for both programs to work!!! I never had both installed at once to avoid conflicts. Any ideas? Red.
