I am having a problem watching prerecorded programs ending early on our 722k. The programs are stopping anywhere from a few seconds up to two minutes before the programs are over, thus I miss the endings of the shows. This seems to be mostly with HD programming, it appears the dvr timers and the program clocks are out of sync. The only response I get from dish tech support is add time to the end of the timer. This will work but it ties up the timer so it runs over, preventing you from starting another show. You will get a time conflict message. I record nearly everything we watch for later viewing, so much of the time both of the timers #1 and #2 are in use, preventing any extension of time. This has been an issue for a long time and I am wondering if anyone has any information on it. Have had the same problem on 722 and 622 models as well.
