Comment (by paladine at naked-geek.net):

 This patch didn't fix the issue for me.  I am using "No Grabber" as I am
 using Sky TV connected to a PVR 150 via SVideo In with no IR Blaster.
 This apparantly makes MythTV automatically assume a program change 2 times
 an hour on the 00 and 30 during LiveTV.

 This does not happen every 30 minutes, in fact I have managed to go upto
 90 minutes before the freeze occurs in LiveTV, however, more often than
 not it happens every 30 minutes.  It does continue to record the signal to
 file and I can watch the mpg from an external program (such as VLC) with
 no issue, sound is synced with the video and everything is perfect, so it
 is just LiveTV that is freezing.

 I spent a lot of time with some people in the #mythtv-users channel
 yesterday (thanks to everyone who tried to figure this out) but I figured
 I should officially update the ticket.

 This problem does not occur when I am watching a "Manual Recording", it
 only occurs in LiveTV.

 On advice of Sphery I tried adding /bin/true and /bin/sleep 5 to the
 configuration but again, this made no difference.  It just happened again
 as I was typing this message, below is the output from mythfrontend:

 As you can seefrom the timestamp 2006-09-16 19:00:15.021, the only way to
 resume LiveTV is for me to exit back to the Mythfrontend Menu and then go
 back into LiveTV.

 Please feel free to email me if you require any more information, with
 instructions for debugging  (I haveonly been using mythtv for about 36
 hours) and I will be happy to run any tests you require and send back the
 results.

 Thanks

 Paladine
