On one of my two HR20-700's, my playlist freezes when ever I try to go off the first page. I can arrow up and down, open folders and even play anything on the first page of my playlist. As soon as I try to either arrow past the last entry on the screen, or page down, the playlist freezes up. I can exit to live TV, change channels, Record, Trick play, etc. The guide even works as expected, going up or down by pages or lines and tuning to a channel when selected. When I press list again, I either see the frozen playlist with the highlight still where it froze up, or I see a partial list with a few items or no items. Either way still frozen and unable to move. The power button LED flashes showing that the DVR received the signal too. I have changed my playlist option to Local playlist only on both DVR's and performed 4 RBR's already. Right now I am doing a surface test on the HDD, but thought I would bring this topic up in case anyone could give me some ideas or things to try.
