[mythtv-users] HD3000 recording problem in Mythtv- signalStrengthATSC_v4l2(), error: Invalid argument

[Brad Fuller]

Howdy all,

I can now view HD3000 signals outside of mythtv (YEAH) but I cannot 
record HD3000 signals inside of myth.
I'm using OTA for HD3000 and cable for PVR250 - both in the same box. 
PVR250 records fine (although it's labeled as Encoder 2 on mythweb and 
the HD3000 is labeled Encoder 4. Strange.)

I'm wondering if it is something to do with the tuning or the device 
assignment or both

Potential Assignment problem:

When playing outside of myth (with mplayer) the HD3000 device is:
/dev/dvb/adapter0/dvr0

But, mythtv-setup indicates an error about not being able to probe the 
inputs. The permissions on the directory and the devices are the same as 
my PVR-250 (video1). I also tried it as "root" with no change.
It does let me assign it to video32 which seems to be a device that 
others have used. I don't understand this.

The HD3000 is assigned to a Video Source Setup (called "terrestrial") 
that connects to Zap2It programs of Local broadcast. The tuning table is 
us-bcast.

I think this is my main problem.

----
Potential Tuning Problem:

I have a list of azap channels in my ~/.azap directory. Can someone tell 
me if MythTV uses this table?

I created a HD3000 card in mythtv-setup and assigned it to bcast. I 
created a new Zap2It entry for broadcast TV and assigned this to the 
HD3000 card. It seemed to dnl the program data fine as the program guide 
has terrestrial channels like 3_1, 4_1 intermingled with the regular 
cable channels.

But, when I try record something on a ATSC channel even though the hard 
disk grinds away and MythTV thinks it's recording nothing shows up and 
the .nuv file is empty. This is the relevent mythbackend log:

The program that was suppose to record is on channel 7-1 which is KPIXDT 
in Zap2It listing, and "KPIX DT" in azap (if that makes a difference).
