Good point. Actually it has values for "Always", "Live TV Only",
"Never". I suggest set it to "Never". I use "never".

Another thing - if you start live TV and get the stuttering, can you
exit from Live TV and go to the recording list, press Menu and "Change
Group Filter" select "LiveTV" then find a recording with very recent
time that corresponded with the stuttering and watch it again, see if
you still see the stuttering. This will help find out if it is the
backend or frontend causing the problem.
