I am using an M10K. I have had a series of video stuttering problems,
which I have mostly worked through. The one you describe is the like
first one that I had.
In my case, I was still setting up, and experimenting, and had not yet
set up the audio out yet. I had installed for ALSA, but my settings
where still for /dev/dsp, which I got a warning about every time I
started playing something. The video would pause just as you described,
until I went in and changed my audio options to use ALSA, at which time
both the audio worked, and that type of video stuttering stopped.
Also, what type of tuner are you using? Another source of stuttering
was the ivtv driver, which doesn't quite support VBI yet (sounds like
it is getting very close, but definitely didn't when I was having the
problem). When I ran the mythtv setup, and turned VBI to NONE for my
ivtv cards, all but the slightest stuttering was gone.
The only stuttering I have left happens for about 15 seconds every half
hour or so. The CPU is normally 80% idle during playback, but during
this time it is only 10% idle. It lasts for such a short time, and the
the stuttering is so light, I haven't taken the time to really dig into
the problem.
Hope that's what you're running into, it's an easy fix.
