Can you tell me what options this actually changes on your receiver?

Looking at mine and following the script, it is trying to change some 
local tv scanning options and I am guessing that is not what it would be 
doing on yours.

If you can tell me what it is really changing, I am sure I can adapt it.

Thanks,
