Comment (by bjm <bjm at lvcm.com>):

 First, there is a typo in my test case. It should say to press "->" or
 Right Arrow to advance one frame at time. Greater than ">" advances one
 second and is working properly.

 For mpeg2, I can verify that with the temporary patch, frame advance does
 advance and decode frames properly although more slowly and unevenly than
 in the past when the key is held down.

 However, frame advance doesn't move at all for software encoded mpeg4 as
 of [8399].

 Note the desiredFrame and framesPlayed is 16141 for all three key presses.
 The picture appears frozen though I suppose it has redrawn the same frame
 three times.
