WOW
What a treasure chest of help.
Thanks.
My supervisor used WMC to un-check the channels. Didn't take her very long, 1-2 minutes.
She had gotten used to the Comcast box so she knew channels numbers very well.
Will have to try the multiple "favorites" style of listings.
This is the remote she is using.

Maybe, as she gets more experience we might upgrade to a fancier remote.
Haven't installed Guide Tool yet.
Got to spend some time over at the WMC thread. But HolyKow there are 4535 postings. Lots of reading.
I've been going thru Assassinn's setup and have made some of the changes. Still lots of his "features" to add.
The focus has been just getting basic TV functions to work smoothly.
So, for now I'm laying low on this Prime Thread unless something comes up Prime related.
But, before I go.....
2 questions:
A) The volume (TV speakers) needs constant changing between channels. One channel is OK then switch channel and the sound is too much. Switch to another channel and it may be even higher or lower or the same. Haven't analyzed it yet at to certain channels. Any ideas? I didn't happen with the Comcast STB.
B) The picture quality is sharp as a tack when the Guide is showing. But the actual TV picture is not sharp. Kinda like not enough pixels. During the initial setup I used the Intel Graphics i3-3225 to set the margins since there was lots of overscan. Any thoughts?
