With the use of digital programming this kind of stuff will happen, especially when options are provided. These receivers are special purpose computers, and the software is continually being updated to provide more options. This is great, but confusing, and aggravating when a new piece of software has a previously non-existing bug. My 722 receiver is frequently doing something that surprises me, but then I realize I've sat down on the remote or something equally dumb like lay it down upside down on the arm of my easy chair.
However, something that's bothered the heck out of me is the reverse-play sequence. For some reason, when I've been reversing to catch a replay of something I wanted to see again (or that happened when I was in the kitchen, like a golf shot), I make the run back to the correct place to start but when I hit the play button it jumps back in time about 2 more minutes. Then if I try to jump forward, I jump right over my desired starting point, and have to start reversing again. Really aggravating.
