We've lost the ability to record and then play. Previously all worked fine and we can still play DVD and tapes. Recorded attempts are just snow. I moved the unit to another TV and only get snow. Some sort of seting or hookup but I can't figure it out. The channel on the unit is 3 and the TV 4. I can't get a 4 on the unit. We run a satellite to a box, cable from box to unit and RWY cable to the TV. Any ideas? Thanks rlpace@aol.com
