Hmm...well stupid me didn't see that there are a few discrete things on the original remote, but now I've combed over the manual and still can't find an adequate solution.

I can set discrete inputs for only 2 inputs via the original remote, but the remote codes stay the same, because the TV saves which inputs they change :(

Also, the remote has a "TV" button which turns on the TV but doesn't turn it off...However there's no button just to turn it off.

Any suggestions welcome...I'm betting this TV is just so new, the codes aren't out there yet.
