 The changes introduced in r11013 cause me an intermittent problem with
 both live TV and recordings.  On changing channels, or on skipping through
 a recorded programme, the video and audio freezes, and the log fills up
 with:

 "NVP: Timed out waiting for free video buffers"

 I was unsure as to the exact cause of this problem, but after backing out
 the changes in this changeset, I am unable to reproduce the problem, so
 I'm fairly confident that somehow this change is the cause.  There were
 some posts on the dev mailing list about others on Intel Macs suffering
 from the exact same symptoms.

 I have no crashlog to attach (as the app just freezes), but I will attach
 a verbose log from the frontend when I get home this evening.
