Hello,

I am stuck installing my HDHomeRun with mythtv. The HDHomeRun is connected to Cox Cable to record the unencrypted HD channels.

I followed the only instructions and did a channel scan with the following results

mysql> select chanid,channum,freqid,callsign,name from channel where sourceid = 3;
+--------+---------+--------+--------------+--------------+

If I scan with "hdhomerun_config 1011C08C scan 0 tuner0.txt" I find a lot more channels including the following programms on channel 83

SCANNING: 579000000 (us-cable:83, us-irc:83)
LOCK: qam256 (ss=90 snq=95 seq=100)
PROGRAM: 2: 0.0
PROGRAM: 3: 0.0
PROGRAM: 9: 0.0

This matches the channels from the silicondust homepage "http://www.silicondust.com/hdhomerun/lineupui?Cmd=LocationProgramsWeb&Country=US&Postcode=xxx"

qam256	83	2	NBC1080P	1920x1080i 16:9
qam256	83	3	CBS1080P	1920x1080i 16:9
qam256	83	9	PPVP	528x480i 4:3

If you look at the mysql table above the channel numbers mythtv found are totally different.

Does anybody know what is going on here?


The online installation instructions say:

"Create a channel lineup and enable/disable channels based on channels listed in the Channel Editor in mythtv-setup.

Note that MythTV uses the ATSC channel numbering as specified in the transport stream, not the remapped cable channel numbering so you will need to select OTA/Antenna as the source in Zap2it. "

Easier said than done :-). The local broadcast listing in schedules direct have the following channels and the channel numbers don't seem to have anything to do with the channel numbers above. 

Intuitively one would think that I have to use the Cox Digital Cable channel lineup but how do I match up the channels from the regular cable channel numbers to the mythtv "83#2" format?

Can anybody please help me. Is there a howto somewhere?

Thanks a lot!
