I've come to notice that avi files are starting to lag when using SiB / Mplayer. By this, I mean that the video slows down sometimes while the audio plays normally. After some point, the video will speed up to catch up to the audio. Then the process repeats. If I have the "Drop Frames" option selected in the settings, then video plays back very choppy while keeping up with the audio. This used to only happen with mkv and certain other file types and did not happen with avi. Anyone know why its starting now and how to correct it?
