[mythtv-users] HD-PVR audio sync issues

Hello,

I recently made the transition from cable to dish network.

I am running Fedora 14 with mythtv from rpmfusion 0.24-2.fc14.x86_64 
packages.

My backend has two HD-PVRs connecting to dishnetwork vip 211k receivers 
using SPDIF.

I am having bad audio sync issues.  I see it in two cases.

1) When changing channels the audio is off by about 2 seconds.  This can 
some times be fixed by changing to a different channel and back, but not 
always.
2) Watching a show for 30 minutes will result in 2-3 second audio lag by 
the end of the show.  Exiting and coming back into the channel fixes the 
issue.

I see lots of posts from people who are using the HD-PVR, so I am 
guessing I am missing some simple setup peice.

Any suggestions on how to eliminate the audio lag issues?

Michael
