After that, I've been unable to get the DIGITAL channels back at all, even going back to factory presets and leaving the unit unplugged for a while. When I do an 'analog/digital' channel scan, it goes through all 125 analog channels then hangs up - displaying only a black screen with the DTV 1.1 and 'now scanning'. The analog channels are all fine.
The "E40" is a program overlap... from the manual:
"E40 Some portion has not been recorded because of program overlapping. Recording did not start at the start time."
That doesn't explain the digital channel disappearance.
I think you had a 3575 first and it apparently worked OK since you described some recording you'd done with it, and the 2160 worked OK when you first got it, correct?
Now, I'm thinking the addition of the splitter might be involved, so try going back to just the original 3575 with NO splitter. Do an Analog/Digital scan and see if things hold as they did before. Maybe use a diff. cable also, and make sure all connections are tight?
If that works, add the 2160 inline, no splitters, and see what happens with its channels. See Kansas-Tom's post below and try his order: 2160 to 3575?
Digital channels can go blue-screen from a signal that's too strong or too weak.
