OK. I did some experimenting and this is what I found. The program where I have been seeing the black screen most often is Justified on FXHD. I started through the program while checking the resolution during the program as well as during commercials. I had Native set to ON. The program was running in 720p as well as most of the commercials. A few commercials were running in 1080i, and that's where the black screen would start and stay black until well into the program material. That's using FF2. Once the program came back I could rewind back to the beginning of the segment without losing anything.
Then I turned Native OFF, with just 720p and 1080i for resolutions. The black screen problem was GONE! Here's the weird part. The program material was now running in 1080i instead of the previous 720p. So it was 1080i from beginning to end, which probably explains why there was no more black screen because it was no longer switching between 720p and 1080i.
Anyone care to explain why the program would appear to be in 720p with Native ON, and 1080i with Native OFF? Is it really in 1080i, or is the Genie just fooling the TV?
If you go into resolutions and uncheck the 1080i all will be shown in 720p if it is the only resolution checked.
Using the old remote you could change the Format when the Native was set to OFF. It would cycle thru each Format available for each resolution you have checked in your setup.
Edit / Add:
For the newer remotes, RC7? models, Try this with Native OFF and the 720p and 1080i resolutions checked.
Press Info, Up Arrow, Right Arrow over to Audio/Video and choose Change Resolutions & Format
This should do the same thing that the Format button on the older remotes does.
