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
The HDHomerun lineup (via the link above in my original post) shows the
following for those channels (I assume):
qam256 113 1 WPVIDT 1280x720p
qam256 113 2 WCAUDT 1920x1080i
qam256 113 3 WPVIDT2 704x480i
qam256 113 4 WPVIDT3 704x480i
qam256 113 5 WCAUDT2 640x480i
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
Thanks alot for all of the help.
