Twice now I have turned on the receiver (HR54) and it was recording one program, I went to turn the channel and at first it wouldn't let me and shows me that it is recording a program, then another tuner shows up and says it's unassigned and to use that. So I try that option and then it tells me it's unavailable. So basically I was locked into that one program that was recording unless I stopped the recording. I do have an HR24-500 in the bedroom, don't know if that has anything to do with it but I figured that would just offer more tuners. Any help is appreciated. Thanks.
