Comment:

 (In [8286]) Fixes #813.

  * Delays the ringbuffer ready flag in one instance.
  * Delays RingBuffer switch if more than 256000 bytes remain in the
 RingBuffer; even if there are less than three valid video frames.
  * Increases RingBuffer retries on RingBuffer switches to approximately 5
 seconds.

 The RingBuffer switch threshold of 256000 should really be keyed to the
 bitrate, but I'm not sure exactly what it should be. This is just double
 the value used then 3 valid video frames remain. This change is needed so
 we don't switch prematurely when using XvMC, or when playing back on a
 marginal system with XVideo (i.e. a 1080i stream on a debug build, running
 on a P4-2800).
