VewDew said:I guess I need to connect my harmony again. I have the 688 and it does work on the HD tivo but not very well. There is an extreme delay between me pressing a button and something happening if it does happen. The 688 worked fantastically on my now defunct Voom setup.
Try changing the batteries first. If there is still a problem call support they can help change delays. My 688 worked fine on Voom and the HD-DVR. I just prefer the 880 due to its better display screen
