Hi Rob,
If you only have 1ME occupies the ME2 timing slot. all other slots work but of course there is no ME1.
I just tested this again on my Carbonite and can route the ME PGM out into MiniME DVE's or Backgrounds without any issue. I also put it into MultiScreen mode with quad outputs and can span the ME PGM across all 4 outs or put it into a DVE that floats across the displays.
So I am not sure what the problem you are seeing is.
If you have skype, feel free to ping me at nspratling.rossvideo.
