[mythtv] 0.19 live tv issue

Mon Feb 20 18:14:31 UTC 2006

I've just upgraded to 0.19, and have issues when live tv crosses show 
boundaries.  I have 2 frontends, one local to the backend, and one 
remote, and they both exhibit the problem.  When a show ends, the video 
freezes, CPU utilization goes to 100%, and mythfrontend starts eating up 
memory.  Hitting escape will go back to the menu, but the memory will 
not get freed.  If I don't hit escape, but just let it run, the frontend 
eventually eats up all the available memory and crashes.  Here is the 
output of mythfrontend --verbose playback:

This line keeps repeating, occasionally interspersed with the following:

2006-02-20 08:30:09.403 NVP: Waiting for prebuffer.. 9 
LAAAAAAAAAAUuAAAAAAAAAAAAAAAuAA

2006-02-20 08:30:09.541 NVP: Prebuffer wait timed out 10 times.

2006-02-20 08:30:09.553 NVP: Waiting for prebuffer.. 0

This is on Gentoo using the 0.19 ebuild.

Any pointers on solving this would be very appreciated.

Thanks
