I do use that tool, but not for channel scans. I use it to extract the call signs, channel ID's and subchannel ID's so I can
untangle the mess that a full channel scan makes.

But that tool does not scan all of the channels, it only gives you the ones that they send to the cheap SD set top boxes, none
of the HD channels, and none of the channels they are giving by accident. Also since I am on limited basic, it says I have all
the extended basic channels that I don't, the ones that are killed by the filter in the line, and the ones that are encrypted by
the cheap encryption handled by the cheap SD set top box.

I also can not use that since I have 5 different channel lists. I have 5 tuners, one on an antenna aimed northwest, one on an
antenna aimed south, and the other three on cable. But one of the three on cable is a ATI HDTV Wonder, so it has to have a
separate channel list from the HDHome Runs. If you are keeping count, I have only accounted for 4 of the channel lists, the
fifth channel list is for the analog part of the ATI HDTV Wonder that I have never gotten to work.

My vague understanding of that long complicated set of instructions for scte65scan makes me believe that method for using
scte65scan for automatically updating the channel list only works for HDHomeRun tuners, and then only if there is only one
channel list. Given that it usually takes a full day to untangle the mess that a full channel scan makes of the channel list,
and the fact that the channel editor for mythweb is borked right now, I do not feel like risking the several hundred correctly
set up channels I now have by attempting to do an automated scan with scte65scan.

Now, if I can figure out what is borked with the mythbackendsetup channel scan and get that fixed, I can do a scan from channel
95 to channel 95, and a scan from channel 99 to channel 99 and have just the channels that need it added to my channel list, and
then I only have to edit 26 channels (one sub channel for channel 95, 12 sub channels for 99, and do this for both tuner types).

Besides, I thought attempting to fix a bug was a good idea.
