[mythtv-users] 0.21: Issue with freezing LiveTV

Hi *,

I have quite annoying issue with freezing LiveTV.

Symptoms:
After launch of LiveTV after some time I get "pause". Usually it is 
after 30min...1-2h.
When freeze occurs I can bring up OSD and OSD shows progress of LiveTV 
buffering but playback time is constant. Behavior is in fact exactly the 
same like paused LiveTV. Pressing pause/play changes nothing. Solution 
is only quit LiveTV and enter again.

I was tested various SVN versions counting that maybe it is bug and 
maybe issue is resolved in newer SVNs.
Indeed in new SVNs I have impression that it happens more rare, but 
unfortunately it is still present.
Now I'm on 0.21-stable SVN 17166.
As problem is quite annoying for family - do somebody have idea how to 
minimize this effect.

My setup:
-Knoppmyth r5f27 upgraded to 0.21 via src compile
-BE is 0.21-fixes SVN 17190, 3xPVR250
-FE is MiniMyth 0.21-fixes SVN 17166 on Abit An-M2HD (nv 7050PV based). 
CPU is AMD X2 4400.

Update:

For nailing issue I launch mm via console.

Observations:

-during play of LiveTV I'm getting mped2video errors on FE, every few 
sec error.

-however playing this exactly record from LiveTV recordings group is OK 
(no errors).

So potential issue place might be:
-hw (i.e. errors on NIC caused by bad behavior of ivtv)
-software (myth running LiveTV introduces errors on BE HDD-FE path).

Currently I don't believe in first one as my BE can simultaneously 
record from 3 PVRs and do network transfers for 3 FE without issues (to 
be sure I will verify it again).

So it looks rather like software issue.

Do You have idea how to further track this issue ?
