I just tested LiveTV with the PVR-150 in Master, and didn't observe any
substantial problem.  Initially there is stuttering because it's trying to
follow too close to live, but pausing a few seconds and resuming fixes it,
even over wireless.

When you see this stuttering, try the following.  In the OSD Playback menu,
select Playback > Playback data, and watch the real-time information
display on the screen.  If the Available Buffer entry is hovering near
0-5%, it indicates following too closely to real time, and you are also
likely to see mythfrontend log messages like "Waited XXXms for video
buffers ..." which just means that the video frames are being starved for
data.  If this is not the case, I would be very interested to get a
description of the kind of data the Playback Data overlay is showing.
