Universal Remote seems to have included the 598 into the updated IR database. No need to download the file from Remote Central unless you want the 'map' document.
With the info on being able to load codes from CCF files (thanks mwiebelhaus) I refreshed all my files for the MX-700 and there it was. Too bad for me was the lack of discreet power codes for my cable box....
Other then that, I've been using the MX-700 for many months now and think it is wonderful. One remote instead of a stack, excellent macro capability, and PC connection to make it easy to configure.
Highly recommended! Hey Meridian, how about adopting this remote? Well, maybe make it the MX-800 to get the RF capability too.
