I've actually got it sorted out! Thanks to a helpful reply at RC forums, I learned that my cable remote was programmable and had the ability to get the codes I needed. I used those and learned them to my MX-500 and now I'm in business.
BTW, the MX-500 (which is going on 10 years old) is finally about to give up the ghost, so I'm ordering an URC r40 to replace it. I'm wanting to move all of my learned codes to the new remote before the MX-500 finally dies and these were the last 2 codes I needed.
Thanks for the reply...

As you probably already know, you can get HDMI1 and HDMI2 with EFCs 162 and 158. The 1994 can't send device 26, but you should be able to learn the signals. If the OEM remote doesn't have those functions, you can enter 5 digit EFCs into e.g Comcast or Atlas cable remotes, or other newer UEI remotes, and use those to teach the 1994.
HDMI1 3 and 4 are 05021 and 03997 using e.g. setup code Audio 1758 or 31758.
