[Bug 548609] Re: 10.04-beta1 hvr-2200 station not getting signal

 

I can confirm that I have exactly the same problem.

I am located in Melbourne, I can tune into all channels except SBS and 9 on both of my HVR-2200 (two cards in system).
I also have a DTV1000T in the same system, which can tune into SBS and 9 just fine.

The signal, snr, ber values coming out of the HVR-2200 driver seem very
different to the DTV1000T i'm not sure if this has something to do with
it, perhaps mythtv is misinterpreting it.

I have had this problem for over a year, ubuntu and mythtv updates over
the year have had no affect on the problem.

The output of tzap scanning SBS ONE on the DTV1000T:

tuning to 536625000 Hz
video pid 0x00a1, audio pid 0x0051
status 01 | signal 0000 | snr 8000 | ber 00003fff | unc 00000000 | 
status 1f | signal 2626 | snr ffff | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal 2626 | snr ffff | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal 2626 | snr ffff | ber 00000000 | unc 00000000 | FE_HAS_LOCK
status 1f | signal 2626 | snr ffff | ber 00000000 | unc 00000000 | FE_HAS_LOCK


The output of tzap scanning SBS ONE on HVR-2200:

tuning to 536625000 Hz
video pid 0x00a1, audio pid 0x0051
status 00 | signal 5454 | snr 0015 | ber 0000ffff | unc 00000000 | 
status 1f | signal fefe | snr 00f6 | ber 00000017 | unc 00000048 | FE_HAS_LOCK
status 1f | signal fefe | snr 0000 | ber 00000011 | unc 00000048 | FE_HAS_LOCK
status 1f | signal fefe | snr 00f6 | ber 00000021 | unc 00000048 | FE_HAS_LOCK
status 1f | signal fefe | snr 00f6 | ber 0000001d | unc 00000048 | FE_HAS_LOCK

the HVR-2200 reports bit error rates whereas the DTV1000T does not, snr
also seems quite low, perhaps the HVR-2200 has a different scale or
meaning for these values.

If there are more test anyone can suggest to perform please let me know,
I have been living without SBS and 9 for so long I have almost given up
on my DVR! :(

Title:
  10.04-beta1 hvr-2200 station not getting signal

Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
  New

Bug description:
  I've just tried out Mythbuntu 10.04-beta1 64bit with the built in driver for the saa-7164.  I downloaded firmware for the HVR-2200, then I had to scan the channels using the scan command:

$ scan /usr/share/dvb/dvb-t/au-Melbourne -o zap -a 1 | tee ~/.mythtv/channels.conf

Then I had to import this in my scan so that I could get channels SBS and Nine.  I've heard that these channels are special in their encoding.   

If I do the normal scan I pick up channels 2, 7, and 10.  The only way I get SBS & nine is through the manual scan.  But when I go and try to watch these stations I get errors.

Here is the output on the command line after starting mythfrontend and going to the SBS channel:

I think the problem is to do with the codec missing
