Matt,
Your screencaps triggered my attention. Got exactly the same problem on a couple
of channels, not all. Do you got those scramble on all channels you tune in ?
Thinking about it I suspect it has something to do with the signal. It worked
fine for years with my single pvr350 and it's probably introduced since my cable
network switched to satellite signals. Got a old square tube as TV and sometimes
when there is a widescreen signal you can see the switch between wide an
standard. Not something one would expect on a standard tube, it doesn't know
about wide screen so the switching must be done at the cable network.
It could be the signal satellite or some other new tech goodies they want to
introduce. All i know is that since the signal is 'different' i got these issues
on some of the channels.
Still guessing here but i don't think the hardware is not to blame because other
channels are fine.
