OK, I just activated the HR10-250 that I bought on e-bay. I bought it because I wanted to experience the DLB everyone is making such a big deal about not having on the HR20. I have two HR20's by the way. OK, my question is: when you change channels the buffers should switch to the current channel and last channel watched, right? I seem to have a problem in that the live buffer starts on the new channel, but the old buffer gets stuck on a channel previously watched, not the last one. Does that make sense? Is there a way to unstick the stuck buffer? Maybe I don't understand the feature well enough yet.
