I would say you are trying to be a DIY, then you are going to have that same learning curve with the Nevo. I have a Samsung LCD that I have loaded the Q50 about 20 times with different IR coding to fine a couple of discrete codes. It does not hurt one thing to 'try' and see what happens.
Start with the T1457. Assign some buttons, click away. If it does not seem to be responding, try the T2286. If that does not work, try another model.
Turns out that Samsung had buttons on other remotes for like a DLP with a discrete button to get to Movie mode, but my LCD 52A750 remote does not have this. However, with the DLP remote code I can take this one item and put it with my programming and have a direct button to Movie mode. Wish I could find a discrete code for GAME mode, but I am still looking for that one.
BE sure to click on 'advanced' buttons when you have some code selected. I have found some additional stuff in there that was not a default button on the remote's and they are discrete one push items.
