AI, W5, and X4 -- issues related to changing EMM providers
I had the exact same issue and tried several rehits on 2 DSR922's (personal and my store's units) as I am a SRL dealer and have WebSAMS access. What I was noticing is that the units were still stuck on the 4096 EMM which is why they were missing all the rehits. You can verify this yourself by pressing OPTION 6 - 7 - 7 - 8 - 1 on STYLE at W5 216. If EMM Provider is still 4096, you need to clear the EMM provider by doing an authorization reset by pressing OPTION 6 - 7 - 7 - 8 - 0. You won't see any feedback on the screen when you do this but the EMM should have been cleared so press exit and OPTION 6 - 7 - 7 - 8 - 1 again and you will see that EMM Provider is now 0. Frequency should already be on 1430.000 if you were still on W5 216 so simply press OK to tune in to this frequency and get SRL to send a rehit to your receiver. Within a few seconds, the EMM Provider should change from 0 to 4160. Once this happens, exit then change to the X4 satellite and your services should be up and running.
I checked all my satellites and there are still there including all C and KU band generics so it appears to be safe to do an authorisation reset.

'AI, W5, and X4 -- issues related to changing EMM providers and receiving hits'
Well this is just my speculation based on scant available data.
Possibly receivers like mine [Early 10yo, GI branded 922] that have an AI tile and a X4 tile may be at the root of the issue.
Mine has AI available when you hit the 'Sat' button
[list order from left to right is W5, X4, AI] on the remote control. But it is NOT in the list of available sats via Options 6,4,4. So it cannot be removed. And my X4 is ch. numbered almost the same as W5. W5 stops at 806, and my X4 stops at 856, and AI [when selected from 'Sat' button on 922 RC, and using ch. up button to increase ch. # before hitting enter] appears to go to 903, but as soon as you hit enter, it reverts to the W5 or X4 channel that you had been previously watching before you hit the 'Sat' button. Meaning you never get AI on the provided data when you are on a channel and touch the 'arrow' [any] key, or 'Exit' key, or 'Info' key.
All very strange and it is a reasonable assumption that these relate to the ability to successfully change over and receive a hit from EMM 4160.
If my receiver wasn't working correctly and well, I would consider changing to X4-216 and unplugging it for 30 seconds and then replugging to see if it uploads Comcast maps and corrects it's map issues.
My 922 has no hits and has not been on any DC2 sat since 12-29-2010 9:58 CST. It has no hits banked because I had a power failure a week ago and my professional APC1400 UPS had failed sometime and I didn't realize it until the power failure. This 922 previously had been subbed to almost all available channels as of early December, 2010.
Questions for 'pwrsurge'.....
1. What was your W5/X4/AI map situation before you performed the authorization reset on the 2 boxes?
2. Was there any old 'Hits' on Options 6,5 before you began?
For anyone that tries the authorization reset you need to collect as much data as possible before doing anything. Such as I have mentioned above. All this may help the Comcast engineers formulate a fix or workaround.
