I'm having a problem playing wmv files in Windows Media Player 10. Whenever I do, they're choppy and slow and play from one still and then show another still a few seconds later. I use GSpot to see what the problem is and it says that wmv9dmod.dll is missing from the Windows>>system32 folder. I've tried uninstalling and reinstalling it and downloading wmv codecs from the microsoft website to no avail. Does anyone know a way to fix this? ETA: Also, the video usually plays like its in slow motion.
