Part of the problem is buggy firmware. The firmware goes too far when it detects any change in a channel's map and rebuilds it completely. Other tuners usually attempt to add new stations, remove deleted ones, or update subchannel labels without rebuilding everything from scratch. They're also more tolerant of glitches, which are bound to happen from time to time.
I know you're on V3 firmware now. I forgot which firmware version you started with, but there should be yet another version you could try, just to see if it helps. If that doesn't work either, I'd consider exchanging the box.
As a follow-up in case anyone else has a problem: I received a response from support with a V1 of the firmware. I loaded it up and reset all the defaults. I then did a new channel scan and this time it must have found EVERY FIOS station available because there was a couple hundred, almost all of which are encrypted and show no picture or sound. It was a huge headache to fish through all of them since they didn't have the nice mappings like 2-1, 4-1, 7-1 of the old firmware (the channels are all XXX-XXXXXX in format). I eventually found CBS, NBC, FOX, ABC, My9, PIX and I even found the Weather Channel and some ION stations the previous firmware didn't pick up. The one downside is I don't seem to be getting any EPG data coming through.
I spent about 3 hours removing the blacked out channels and renaming the ones that did come in as well as adding the commonly used ones to my favorites. I then set up some test recordings that are set to run daily and record 5 minutes from several different stations and different times.
The past two days have seen all the recordings complete successfully, including automatically powering on and off the box. The re-schedules have occurred without corruption as well.
All in all V1 was a ton of work to set up but seems to be working. I don't have EPG but that's a compromise I'm willing to make at this point, especially since it used to update in the middle of watching a show and cause the picture and audio to cut out momentarily when it did.
