As mentioned previously, the problem I am having is due to audio (the
video glitches are due to mythtv trying to keep the video and audio in
sync).

I am still getting this. I tried increasing RAM (from the previous 256MB
to 512MB) this week, in case it was a swap problem. The system is now
not swapping, but the glitches are still there.

The audio problems have been continuously happening in Eastenders (BBC1), 
and have randomly happened with a few other channels (including for 
CSI Miami on Channel5). Most recently (last 3-ish weeks) it has also 
occurred during the reruns of "24" (BBC1, Friday circa 23:45 for a 
couple of hours).

Any other thoughts?

Cheers


Ivan
