Recently built a new XP HTPC based around a 2400XT, BDC-202 and bought and installed the latest PowerDVD. Worked fine but wouldn't recognise an m2ts file I had so I bought the latest version of Nero, installed that and played the m2ts file no problem. I go to use PowerDVD today to play an avi and no joy, won't work. Winmedia plays back but a bit of pixelation. Nero plays back smooth video but sound out of sync/video too fast. Are there known conflicts with having Nero and PowerDVD installed together? I could reinstall PowerDVD but don't want to get in the round robin of installing each player every time I want to test a particular file.
