Your right Lordsmurf, I thought it was the JVC but it wasn't, it was the DTV signal. I only wish the JVC had a TBC like the Panasonic models and then there wouldn't be a problem. That explains why the Panasonic captures were fine while the JVC weren't.

Once I put the TBC 1000 between the signal and the JVC recorder it cleared up. All the channels record perfectly. Tested it yesterday, all day long and found not one single program out of sync.

I think I will write to JVC and let them know that a good TBC added to the recorder is the way to go, even digital satellite signals need help with sync.
