Bought a 5006 from Radio Shack the other day and have noticed a few problems:
1) Timer recording using "Daily" (other choices are "Once" and "Weekly") records 7 days out of the week rather than the expected M-F.
2) Mono tuner was too loud and emitted a hum. I upgraded the firmware and the tuner is no longer too loud but it still emits hum. I realize I can jack in a VCR and use its tuner but who wants to program 2 machines.
3) As has been noted by others, the front jacks are noisy.
If anyone has any solutions to the problems (especially #1 and #2) please advise. I'd like to keep the machine for its great versatility but not if the downsides are unsolvable.
