OK, this works fine. I was not sure why there was a loop around the send command since there is a repeat count parameter. I added defines for all the useful commands and built a sequence of commands that turns on the TV and sets the source to the DTV STB.
I am wondering why I can't find the hex codes for the DTV RC65 remote anywhere. Is there some legal issue?
