Sorry... maybe it is not stuttering.
The issue is that when I see a recording after a while it seems that the
mpeg loses syncro and start decoding incorrectly (squares and gliches).
It only happens with recordings, and AFAIK the signal quality is ok. It
happens when watching recordings from any channel.
P.S.: If you consider it different I can start a new thread.
