Cliff,
I'll upgrade your remote for you, drop me a line, but I doubt anyone would be willing to build a box, even for money, it takes most people two hours to build.

Ian,
If I remember correctly, the RCA video selector has it's own set of IR commands, which it defaults to when it loses power, and these are the same codes that RCA uses as input selects for all it's devices, so you can create those codes right now without a selector box.

Here's how you do it. The advanced code you need is 227, the question is "what's the device code?", here are some codes that you can use:

DVD/0522
VCR/0060
VCR/0202

There are probably more, just pick some RCA device codes and try advanced code 227. (I'm getting thse codes from: [Link: hifi-remote.com]

Now understand that I don't have this video selector (I have the Sima) so I'm just going on what I read in that thread.

Rob.
