Looking for any info about upgrading to a Harmony 880 from the 659. I use separate SACD and DVD audio units. I got one of the new DISH Vip 622 DVRs and will get one of the new Toshiba HDDVDs. I have not got all the DVR commands on to the 659 yet even after trying to "learn" them one by one. Will a new 880 make my viewing/listening any smoother ? Thanks for any help.
