Copious kudos Mr. Worthington, with your help I think I've graduated from a
newbie level -10 to newbie level -9. Most of the problems I had stemmed
from creating a directory, when the wiki said create a file, secondly
creating it outside the terminal caused the ownership issue. DCT700.conf is
now only a file inside /etc/lirc and is owned by root, and even though I
didn't see any light emitting from the IR blaster on the initial tests (I
didn't see error messages either), with one hand holding the emitter on the
STB and the other hitting "enter" for a preloaded channel change command,
shazam! it did it! Again many thanks Stephen. More research and more
tweaking in my immediate future, but I'm over what seemed a major hurdle 24
hours ago.
