I had video playing pretty darn well on this thing for a few days (audio almost synched perfectly with the video, as close as this thing is going to get I gather), then messed around with the 'display options' menu. Unleashed the FPS limit, messed with dithering to see what that was, etc. Didn't like the results because it messed up the audio and video synch (of course). I reset the settings, but the audio/video synch is still way off (as opposed to going back to what it was before I changed the settings). What's the recommendation here experts to get my video back to the default settings? I'm tempted to just reload the latest build and hope that resets things. Since that's easy enough to do, is that the best solution?
