 Provide better seeking and position display for some videos.

 Specifically, there are examples of poorly-encoded avi files that
 report a video frame rate of 30fps but the video stream is actually
 24fps.  Because frame intervals are actually encoded as 30fps, every
 4th frame has to be repeated.  Without an adjustment to framesPlayed,
 translations between MythPlayer's frame-based seeking/display and
 ffmpeg's timecode-based seeking drift out of sync.

 Note: Similar adjustments may be necessary if frames have to be
 dropped due to a frame rate mismatch.
