This last weekend when I installed everything, I was able to watch TV,
but I noticed all the guide data was off by two channels. I decided to
take the "one thing at a time" approach and brought the system into the
office for the week to work out issues with playing movies, mp3's, etc.
The box goes home tonight and this weekend I'm going to re-attempt to
get TV working properly as well as get output to my TV (and not just my
For starters, I'm in North County San Diego. We have Cox Digital Cable.
In my house, I have three Cox tuners/DVRs that each get upwards of 1100
channels. All other cable points in the house get "basic cable"...
channels 0-99. In my living room where my Myth box is going to reside,
I've split the cable feed and have one leg going to the Cox tuner/DVR
and the other to the input on my Hauppauge PVR500 card. From what I can
tell when I compare TV's in the house that are behind Cox tuners to
those that are simply cable ready (getting channels 0-99), the channel
line-up for channels 0-99 is the same. Thus, when I'm using DataDirect,
my line-up is for Cox Digital Cable (note that they offer me two
choices... Cox Cable and Cox Digital Cable... I chose the latter based
on what I mentioned above). I'm thinking, however, that perhaps some of
my choices in "mythtv-setup" may be to blame for my channels all being
two channels off from the guide.
So for starters, in mythtv-setup, under General, what "Channel Frequency
table" do I want? us-cable? us-cable-hrc? us-cable-irc? us-bcast (I
highly doubt this)?
Could the "Time offset for EIT listings" be related to my channels
differing from the guide?
How 'bout "Cross source EIT"? As I understand things, Cox Digital Cable
is actually ATSC???
In the Video Sources Setup should I check "Perform EIT Scan"? Should the
Channel Frequency table match what I choose in General? (ie: should it
be set to us-cable both here and in the General section)?
In trying to resolve all this last weekend, I was switching the Data
Direct sources for my area between Cox Cable and Cox Digital Cable.
Would choosing one, then running "mythfilldatabase --refresh-all" help?
Perhaps I have bogus entries from originally choosing Cox Cable and need
to tell it to get the Cox Digital Cable sources, then refresh it to wipe
out the old crud?
Finally, in mythfrontend, setup, TV Setup, Program Guide, what channel
do I set for the "Guide starts at channel" field? Perhaps having the
guide be on a channel that actually has a real channel on it is causing
Please bear with me... I'm not the most hip with A/V and cable stuff.
And its been a long week of using Myth and trying to get things working
(remote, MP3 collections, movies, etc)...
