OK, I just started trying to map the HDHomerun lineup frequencies (I 
don't have an HDHomerun; only a pcHDTV-5500 card, but their lineup for 
my zipcode is the only source that I've seen where I can see the 
relationship between the transmitted channel and call-sign) to the 
channel names/numbers that I'm familiar with, and I want to be sure I'm 
going about it correctly.  I am using the channel editor via MythWeb.

delete 	sourceid 	xmltvid 	channum 	callsign 	name 	freqid 	finetune 
videofilters 	brightness 	contrast 	colour 	hue 	recpriority 	commfree 
visible 	useonairguide

The HDHomerun lineup (via the link above in my original post) shows the 
following for those channels (I assume):
qam256 	113 	1 	WPVIDT 	1280x720p
	16:9
	
<http://img.lineupui.silicondust.com/snapshots/snapshot_21995.jpg>
qam256 	113 	2 	WCAUDT 	1920x1080i
	16:9
	
<http://img.lineupui.silicondust.com/snapshots/snapshot_20777.jpg>
qam256 	113 	3 	WPVIDT2 	704x480i
	4:3
	
qam256 	113 	4 	WPVIDT3 	704x480i
	4:3
	
qam256 	113 	5 	WCAUDT2 	640x480i
640x480p
	4:3


Do I have to do anything with the finetune column?  I just want to make 
sure that what I'm assuming is correct.  Also, the HDHomerun lineup 
shows alot of 8VSB channels, but when I scan for channels in Myth, I 
don't get any of these.  Only these digital, unencrypted ones (like 
79#0, etc.).

Thanks alot for all of the help.
Harry
