[mythtv-users] Live TV stutter

[Jim Abernathy]

90% of my Mythtv viewing has been recorded tv so I could skip over 
commercials.  However, in the morning I sometimes watch the local and 
national news live with mythtv.  I've noticed that if I select Watch TV 
it will come up on the last station viewed and there is a stutter in the 
picture. It's very noticeable particularly if they have a text scroll at 
the bottom of the screen.  I've fixed this by using the left arrow to 
backup 10 seconds. At that point it's a perfect picture.  To me this is 
understandable and it sort of explains why DirecTV's picture is always 
delayed when view live tv using their DVR versus a standard receiver.

However, I noticed today which playing with mythtv live that if I switch 
to a new channel I do NOT get the stuttering and do not need to backup a 
few seconds.

Is this behavior normal? Does the stuttering point to a setting I should 
change?
