I currently use analog TV for my viewing pleasure. In my area, the cost for
Digital TV is just too expensive, so I have no cable box in my setup. I
split my analog coax line for the mythbox, and the TV. A few months ago,
Time Warner released some un-encrypted HD channels in my area. So I
borrowed an HDHomerun box from a friend to see if it could access any of
these un-encrypted qam channels. Using the HDHomerun_config and VLC, I was
able to view about 5 local broadcasting channels in HD (woohoo).
So, I am followed the ubuntu HDhomerun instructions to integrate the homerun
box with mythtv. The steps were easy to follow, and I encountered no
problems, until after the channel scanning was complete. I noticed that
several channels that were supposed to be listed, were not listed at all.
So, using the homerun_config and VLC, I manually scanned, and recorded all
of the available channels. Here are a few examples:
Channel 88 - 1: 1.1 E1_1 WG -> NBC
Channel 88 - 2: 1.2 E1_2 WI -> CBS
Channel 89 - 1: 1.1 E2_1 WN -> WNED
Channel 89 - 3: 1.3 E2_3 WK -> ABC
I ran the mythtv channel scan again, but this time paid close attention to
the output. Here is what is happening:
Channel 88 - E1_2 WI 1-2 - Added as 1.2 (this is CBS)
Channel 88 - E1_1 WG 1-1 - Added as 1.1 (this is NBC)
Channel 89 - E2_3 WK 1-3 - Added as 1.3 (this is ABC)
Channel 89 - E2_1 WN 1-1 - Updated as 1.1 (This is WNED)
I'm not exactly sure what's going on here, but it seems that when myth
scanned channel 89 1-1, it matched it with channel 88 1-1, and updated the
channel data to point to channel 89 instead of created a new channel id.
I've seen in the mailing list that some people are creating their own
channels by modifying the database directly. I'm not opposed to this since
I only need to create 5 entries for the valid channels I want, but I don't
know how to do it. So, any help with either fixing the channel scanning
problem, or manually adding the channels to the database would be extremely
