Clearly I made a mistake and duplicated one of the codes.  But comparing your first code (Speaker Preset Toggle - 891) to mine, the only difference is the last byte (D vs. E).

Here is the line from the manual:
RCKSK0410891       1101111011**********       Speaker Preset (Toggle)

And here is how I entered it in the Pronto Hex Generator:

As you can see, it's generating the exact same code with an "E" in the last byte.

Did I miss something?  Is the Pronto Hex Generator not working?  I appreciate everyone's help.
