Jon,

Thanks. The "Tuner" discrete seemed to do the trick for me.

It would still be good to be able to find a good table documenting these Sony TV codes - even though most of my other "learned" codes seem to work OK, it looks like several of them (not available in the "discrete" list) are real long codes (probably because I held the button too long?). I'd like to go through and clean these up at some point, but it would be nice if I had some documentation to do it by ... not trial & error.

Anyway, thanks. I'm up and running now.
