I just got 2 new 612's. On my other receivers I just the jump ahead and jump back buttons to skip commercials when watching recorded shows. I think it jumps ahead 30 seconds and back 10. Never had a problem before but with these 612's it seems to not work as well. Sometimes when you go back it will go back a more like 60 seconds and will jump way ahead, kind of unpredictable, making it hard to skip through commercials. And when it starts to play after skipping ahead or back it kind of skips or stutters a little and then plays fine. Since it is happening on both I would assume is not likely an issue with both, maybe software? Has anyone else seen issues like this?
