I spoke on the phone with a rep (or I should say, I was on hold with a rep) for about 30 min, from 4:30 to 5:00 when the repair guy was due at 5. We finally agreed to reschedule the appt for Monday when they should (hopefully) have more dual-channel DVRs in stock.
I didn't think that the "Record Season" option was a dual channel thing though, just the Record while you watch something else option.
And really, it's the "Record Season" feature that I'm most missing.
Side Note: They called again while I was downstairs to "confirm" the appointment, that makes 4 times. Dept of Redundancy Dept anyone?
