[mythtv-users] Playback short pauses - remote frontends

This problem started about 3 to 4 weeks ago whilst running 0.23 + fixes. 
I've run this system without problem for a number of months. I've not 
made any changes apart from running updates (I don't remember the 
problem starting with a specific update). I have a combined 
frontend/backend with 3 separate frontends. The combined 
frontend/backend works without problem, the short pauses on live TV or 
recordings occur on all  3 separate frontends, behaving in a similar 
manner. They are noticeably slower to connect to the backend since the 
problem started. The pauses start within seconds after playing live TV 
or watching a recording and continue until you exit. I have updated to 
0.24 + fixes on Ubuntu 10.10 with no change to the pause problem. All 
frontends/backend are connected over gigabit ethernet; I don't believe 
there is a problem here. Although similar to other posts, I thought I 
should post separately, I hope that was the correct thing to do. I am 
including the terminal output from running a remote frontend, I hope 
this isn't too much text to include on the list.

Thanks for looking.
