Jason, I did experiment with longer delays (up to 2 seconds), but that did not solve anything. The macros are very simple - they switch a Marantz A/V receiver input and switch the Samsung TV input, then jump to the appropriate device panel. I didn't play around long enough to investigate further. I think it's really odd the emulator bombs out, and the remote just stops executing the macro. I had previously setup a macro scheme where I change inputs automatically calling separate macros that change the input from a known input. This works very consistently, so instead of troubleshooting the problem, I went with my old method. I just substituted the discrete alias within my macros to an alias to a input changing macro. This works great, but I would like to get the discretes to work. I'll have to try again the next time I run across a Samsung DLP.
