[mythtv-users] Sweet! PC HD3000 QAM_256 working, now about importing those channels?

[Brian McEntire]

Thank you for that QAM scanning script! I ran it and I'll include the 
results below...

Are you sure? I think I've seen many posts about cable operaters not 
providing PSIP information. Here is the output of channels.conf generated by 
the script you attached:

[000-0001]:561000000:QAM_256:16:17:1
[001-0003]:561000000:QAM_256:144:145:3
[002-0002]:561000000:QAM_256:80:81:2
...

There are about 15 more entries, but the top three ought to be enought to 
discuss.

1) Is the left most field what you would expect to see? How about the rest 
of the lines?

2) I tuned into those channels by "name" (ie [000-0001]) and could watch 
some of them with Mplayer. I could watch NBC, ABC, CBS, and FOX which I 
expected to be in clear QAM. The rest were probably encrypted because I 
could get a lock but couldn't see anything.

In the output above, the first two are viewable with mplayer, the last is 
not.

And if not? :) ... This must be where it gets tricky.

I tried doing a manual transport scan within the channel editor and I 
selected one of the frequencies above which I new I could view with mplayer. 
This kinda worked, but Myth made weird channel named, literally like "2#2". 
I could actually tune to one or two of them and watch them within Myth, 
which is very exciting, but the guide data was wrong and two others wouldn't 
tune, so I'm not there yet.

Go to labs.zap2it.com <http://labs.zap2it.com>, add those channels to

Okay, I was able to do that and get the XMLTV IDs. On the other hand, this 
didn't help get the guide data into the imported channels and also doesn't 
help them tune in any better. (Maybe a more experienced Myth guru wouldn't 
expect it to :)


So anyway, I'm getting there. If anyone has any more ideas, please let me 
know. It feels tantilizingly close since I can tune channels manually and 
watch them, it seems like it must just be a matter of getting the channel 
numbers and such into the right format for Myth to understand.
