I recently purchased the Samsung LN52B750 to replace my old tv. I started noticing problems with the Dish remote within a couple of days. As mentioned in a previous post, changing the backlighting settings does seem to make it better (in my case watching in standard mode instead of movie mode). However, the solution is to call dish and ask for a UHF remote. They will send a new remote package that includes different "receivers" for the 722k that will not be counfounded by the IR emitted from the Samsung TV. Hope this helps!
