Been there, tried that, still no joy. Used "Method 1" and "Method 2" I found here. Downloaded a load of new codecs. Updated video drivers. Turned off harware acceleration, turned it back on again.
WMP still crashes whenever I try to play a file. I cam open WMP, and even see the library items. Just can't play them. I have Win 7 Home Premium 32 bit. Athlon 4000+, 2 Gb RAM, Geforce 6800GT video card.
WMP works fine on the other PC (lesser spec and same card). I suspect something is corrupted in my version of Win 7. Any suggestions gratefully recieved, please! I have downloadedVLC, but I just want to get this long-standing problem sorted. IIRC, WMP 12 has never run corrrectly on this machine.
