Scanning the ether is exactly what is broken right now.

Looks like I did not make myself clear enough.

It is not the list of my channels that is corrupted, it is the list of channel numbers and channel frequencies that channel scan
uses to scan for channels that is broken.

For instance: If I choose to scan for channels and choose "Cable" the list of channels to scan contains only channels 2 through
83. It is not possible to choose channels above 83 to scan. Also if I choose "cable" the stop channel drop down menu starts out
empty instead of showing the highest possible channel like it does for all other selections.
If I choose "Cable High", it shows channel number 78 as the start and 159 for the end, but if I look at the actual list of
channels in the drop down boxes, channels 95, 96, 97, 98, and 99 are missing, so there is no possible way to scan those channels

Given that neither the channel editor, nor mythweb will allow access to (or even show) the subchannel, it is now impossible for
me to add channel 95 which comcast in their endless game of musical channels added about a month ago.

So, if someone would give me a clue where the channel frequency table is that MythBackendSetup uses to scan for channels, I
would very much appreciate it.
