Thanks, I restored commands to default and it works...sort of. Channel up is down and vice versa. But I can look for help on that one.
Just for clarity. I use a Harmony 880 remote usually, but have an MCE remote as well. Both operate the same way for me.
In the Guide the Channel Down button pages down the list of channels. The Chanel Up button pages up the list. As the Guide is sorted from lowest number channel to highest number, pressing channel down actually highlights a higher numbered channel.
When watching a channel live, pressing the Channel Down button decreases the channel number that I am watching by one; So if on Channel 10, MC move to Channel 9.
Pressing the Channel Up button increases the channel number that I am watching by one; So if on Channel 10, MC move to Channel 11.
This is what I would expect it to do.
There is no Previous/Next button on the MCE remote, or at least none labelled that way. On the Harmony 880 there is a previous button, but it is always used to go back to the previous function I was using, like the back arrow on an internet browser, or the Back command in MC, which is how I use it. On my Samsung TV, that Prev(ious) button is defined as ChannelPrev(ious), which is consistent with the PVR I used to use. i.e. The Prev button takes you back to what you were previously watching. I just have that button mapped to Back on the Harmony now, for MC use. So I don't know if MC uses internal commands of Previous/Next, but the Harmony sends ChannelUp/ChannelDown commands to MC, and to the TV when I use it directly.
So are the Channel Up/Down buttons actually reversed for you, or do they just work differently to your expectation?
But when I do change channels it does sort of a dub step (not sure what else to call it). When I change the channel it sort of sounds like it is skipping and repeating for a second.
Some tuners do take a little while to change. The skipping repeating sound is MC synchronising the video with the sound from the OTA signal. If you say what tuner hardware you are using, someone with the same hardware may be able to comment on what is normal for it.
