My freezing issues with my 34 seemed to be fixed with the two software releases prior to 870. But after that was released I started seeing it on ( AGAIN )
NBC shows. So I gave up and called in for my third time requesting a visit and replacement. Soon as the guy got here I went out to the truck to meet him, told him about the freezing issue, and he just reached back and grabbed a 44 and replaced mine. I do believe that the 870 release that was to deal with the auto delete issue (re)introduced some other issues. The 34s seem to be affected more severely but I think the 44s are getting hit as well. If you can wait out one more software update ( there have been a lot this year ) see if your issues pop back up. If you can't wait and the issue becomes bothersome again, call and request a visit. My impression from this installer and several others I've spoken to in the last month or so ( a lot of new neighbors ) is that the 34s are pretty much being gotten rid of and they only have 44s on their trucks.
