I have a similar problem with my HPRSLNG. I have a timer set for Deadliest Catch on Tuesdays. I use the DVR to record only new shows. Tuesday night is a busy TV night I have several shows that I watch. The DVR has to record three of them for me. Since the DVR can't record all of them at once I select Deadliest Catch to be skipped. I then check to see that the DVR picked it up at the 11:00pm showing so I won't miss the episode.
That works great for one week. The next week I find that the show was not recorded at all. I look for the timer and scan for the next event and I get No events scheduled. After checking the guide I find that the next new episode is in the guide, labeled as new yet the DVR is not set to record it.
In order to fix it I delete the old timer and set a new one. Come Tuesday night I have to skip it, then it records the later airing. Timer again wo'nt record beyond that.
I could set the timer to record reruns but then I spend a lot of time cleaning up the DVR and also causes conflicts on other nights.
I never had this problem before the resent software update.
I have chatted online and on the phone about this problem. I was once told that it was a known issue that they were working on, but it still has not been fixed. This has gone on for at least 19 weeks during the latest season of Deadliest Catch.
This my occur on other channels as well I just don't have any other conflicts than on Tuesday night to test this on.
