I have been using VLC successfully for a long time on XP. When I recently switched to windows 7, keeping all the hardware the same, I'm now getting "tearing" (the appearance of horizontal lines) on shots that have a lot of horizontal panning. I tried to find information about this on the web. One thing I found was the instruction to confirm that my windows 7 refresh rate matched my video card refresh rate. So my video card said 60 and windows 7 said 59. I set it to 60 in windows 7 and the screen went dark for a moment as though it were recalibrating, but afterward Windows 7 still said 59. I read somewhere else that this isn't important. It has to do with the real refresh rate which is a decimal somewhere between 59 and 60 and how the video card just rounds off the display differently than windows, but in reality they are the same rate. I don't know if that is true.
Anyway, any help appreciated. What should I try next to debug this issue?
Incidentally, if I give up on VLC, are there any other free video players that are known to work without issues on windows 7?
