I think it's the VIP722. It's the black one.

Every now and then I will notice that a show has not gotten recorded. I don't notice it until after the next day or two or if I get a news article talking about the show, or a board posting.

I go into the DVR setting and it says "Deleted by priority". This "Priority" deal is really getting on my nerves, because the HD-DVR is not abiding by the priority I've set. The show that most commonly gets deleted is #5 on the list, the 4 shows before it are single run shows all on different channels and none of them are happening at the same time.

Near as I can figure, whenever there is a Mythbusters or Law & Order marathon and it's recording multiple episodes of those, it overrides other shows due to both tuners being used at the time. The problem is that if I told the HD-DVR that another show has priority, it should not be recording the MythBusters/Law & Order episodes that are occurring at the same time, yet it seems to not want to follow my rules. I never had this issue with the DirecTV HD-DVR, the Time Warner one or the Cox one.

Any ideas?
