I wanted to dust this thread off and state that the problem continues to occur. The Dish Engineer and the CEO Rep will not reply to my E-mails and as far as I know, no one is working on fixing the issue! When the problem re-occurs, I phone Technical Support and report the specific event. Without exception, the CSR can find no documentation of the problem and try to get me to do a power cord reset or some basic trouble shooting.
Again, the problem is unique to the 722k. Occurs infrequently... maybe twice a month. Occurs on OTA recordings and also on Sat programs. When it happens, if my 622 was also recording the same event, that recording is normal... it is only a 722k issue.
When the problem occurs, the list of recordings displays the event as seemingly normal. An hour show might show the duration as 1 Hr 4 Minutes. However, on playback at some point in time (As little as one minute, as many as 50 minutes after start) the video just jumps to the end screen - the one where you may indicate done, protect, erase, Start Over, etc. If I skip back from the screen, the show will resume for a few seconds until it reaches the same point where it skipped ahead previously and again jump to that end screen.
I wish one of the DIRT Team members would roll with this.
This has happened a few time to me as well on my 722k.
Never on my 622.
