I remember when I had a 922, that you could turn off the 922 and wait about 30 minutes and it would update on it's own. Don't know if it still works that way though.
It still does,but the issue is deeper than that,people need to access what is happening and make the proper adjustments.Dish is beta testing the Hopper and Joey,it has PTAT which has to do with locals on satellite.I see changes in my guide every day and sometimes several times a day in my guide with my HD locals,while I don't see any problems with my SD locals.
I bought my 922/wMT2 because at the time it was not offered by DISH,I wanted the new format to see and test it for myself.Here is my solutions to the problems I have seen:
I took out my MT2,to be reinstalled at a later time when issues subside.
I set up my local channel timers to use my SD channels only(setup guide option for SD&HD).
Make sure my guide list is always set to My Channels,no other option.
I do not do a Favorites List because it will get jumbled up with these issues.
I try to stay away from going into Duo Mode when I do I lose timers.
These are a few of my solutions to make things work right on my 922,the people that are running the 722k are also experiencing similar issues.
Good Luck!.
