I just purchased the Harmony 880 this week. I am having a slight problem with it though. I watch HD over OTA and I also have Digital Cable I watch over the QAM tuner. Every time I pick the "Watch TV" activity on the remote though, it always switches to the Digital Cable, no matter what I was watching earlier. i.e. I turn on the TV and start watching an HD channel over OTA. I finish watching and shut everything off. I come back a minute later and pick "Watch TV" again and the TV is on a digital cable channel instead. Anyone know the cause of this?

Do you use the same TV input for both activities? Does the original remote do the same? If so then check your TV features.

Yeah it's the same input for both. If I go to the "TV" input on the original remote though it goes back to exactly what I was watching. Doesn't change to the Digital Cable. There are also 2 separate buttons on the remote for the 2 tuners in addition to the "TV" input, but the actual "TV" input always switched back to exactly what I was watching. The same input on the Harmony 880 always switches to Digital Cable though. Any ideas?

Sounds like the activity setup for watch TV is either selecting the wrong input or the input selection command is sending the wrong or too many commands. Re-check the input setup on the TV device and re-run the activity setup on the watch TV activity.

Check, in device mode, that the command used for the activity does the same as the OEM remote. If not, re-teach it.

Unfortunately I can't reteach it. It's a discrete code. The button doesn't exist on the original remote. Guess Logitech must have programmed the discrete code incorrectly. I have emailed them asking them to fix it, and hopefully I they will fix it.

Try all the commands (like InputAntennaA, InputAntenna2, etc.) in device mode.

I'm not new to this. I of course tried every single command on the remote before posting here. Like I said, Logitech programmed the InputTV discrete code incorrectly and I have emailed them to fix it.
