Can anyone tell me: 1.) How many devices can be controlled by the Harmony 628? 2.) Can the 628 control HDTVs & HD cable box/DVRs? 3.) How many "activities" can be programmed? The newer Harmony 880 is advertised as geared specifically for newer devices but many customer-based reviews seem to indicate that most of the Harmony remotes are the same basic devices with a few tweaks here and there. If there are any 628 users out there, I have in my system an HDTV, an HD cable box/DVR, VHS vcr, Beta VCR (!), LD Player, CD Player and HT Receiver. Nuttin' too fancy...but am wondering if the newer stuff (HDTV & HD cable box/PVR) can be controlled? I would also want to be able to program at least six activities (probably a few more). Thanks in advance for ANY help you may be able to give.
