[mythtv] wedged in watch recordings

[George Nassas]

Hi, every so often my frontend gets into a deadlock when I'm  
scrolling through the watch recordings menu. I have preview videos  
set to play and it's apparently hung waiting for the preview to stop  
after I've pressed a key to scroll further down the list.

I'm set up for debugging so if there's something I should be looking  
for or I can try I'll do it. Or, I can open a ticket.

The deadlocks are intermittent.
