[mythtv] Prebuffering pause w/PVR-250 Stream - SVN 8896

[Mark Buechler]

You are correct. I looked at the patch and it looks like it has more to do
with exiting. I found that I've been doing streaming ever since I broke out
a slave backend. Anyway, the problem only occurs with streaming. My
work-around is disabling that (which is way better anyway). I'll look
through the patches and see if I can find the culprit.

Thanks Isaac.
