[mythtv-users] Mythfrontend "freezes" watching LiveTV at end of program (as determined by EPG)

Thanks for pointing out that bug report.
I'd found all sorts of other similar ones but had not seen that one yet.
Like lots of the other reports I've come across the symptoms were 
similar but not exactly the same. Symptoms that I experienced that no 
one else has written about include
- my frontend locked up entirely and did not respond to keypresses
- sometimes the backend died as well

Anyway, as a result of reading that report I tried a few of the 
suggestions it contained and found that the
"I have unchecked "wait for SEQ headers" in capture card 
settings>recording options in mythtv-setup." suggestion actually 
resolved the issue.
One of my networked frontend machines has now been through 10-20 program 
changes and been running for 6-8 hours non-stop.
There is a slight pause (about 1 sec) on program changes, but that's all.

Leaving it running for a few more hours has resulted in many more 
successful transitions. One of them however, did "freeze" the screen on 
the front end, but the frontend still responded to the ESC key and so I 
could simply restart the "Watch TV".

This is a significant improvement.

Thanks for the help.
