185.19 to 180.44 screwes up WMV, AVI, MPG video playback....
New issue. Since 185.19 does not work with BOINC due to CUDA issues, I had to re-install 180.44. Now video playback (all formats - mpeg, wmv, avi, etc.) only plays audio, no video. Re-installing 185.19 brings back the video playback, but screws up CUDA for BOINC. I'm assuming something was set in the 185.19 that is not being un-set in the 180.44 re-install. Here's the bug report for 180.44.
