Probably not all that extraordinary but I'm still using PVR-1600's and
PVR-2250's in both of my Backends. Just the digital portions as no
analog stations locally. The original cards were for a MythDora system
-- and then I smartened up and switched to Mythbuntu! The reason for
two Backends is duplicate recordings because of some strange issues with
reception; maybe for a separate thread
As far as the OP's question on stutter of Live TV, I found (years ago)
the 'solution' was to just tap-tap Play/Pause and the
jittering/stuttering would go away. Seems like I read the issue was due
to the the (lag?) time between the write and read functions: took so
many microseconds to do the record (write) process and so many to do the
playback (read) process. Doesn't explain the OP's statement of waiting
five minutes. Possibly the use of an incorrect Video Playback Option?
(Playback Profiles page 3)? Seems like when I had it incorrectly
configured the recorded shows stuttered, though didn't get to Live TV.
