Hello,
I have an HP Pavilion OEM'd HVR-1800 that I'm giving a shot at getting
working (PVR-500 and HDHR are my production analog/digital inputs).
I'm running Mythbuntu 8.04 and have tried both with the bundled
version of v4l-dvb modules and a hg copy from April 29, and both have
the same problem:
The card is detected fine and /dev/dvb/* created. When I run 'scan us-
Cable-Standard-center-frequencies-QAM256' it detects nothing, even on
frequencies which I know are QAM256 from the HDHR which is 12" of coax
away from the HVR-1800. Here is an example from the HDHR scan:
SCANNING: 759000000 (us-cable:118, us-irc:118)
LOCK: qam256 (ss=90 snq=52 seq=100)
PROGRAM: 1: 6.1 WPVI-HD
PROGRAM: 2: 10.1 WCAU-DT
PROGRAM: 3: 6.2 WPVI-SD
PROGRAM: 4: 6.3 WPVI-WX
PROGRAM: 5: 10.2 WX-PLUS
and from 'scan -v test-chan118' which has just 759000000 in it:
scanning test-chan118
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

Done.
I have checked the physical connections best I can. Connecting the
HVR-1800's coax to the PVR-500 sees the analog side of things fine,
and the correct jack on the HVR-1800 is being used.
I'm not sure where to go from here debugging things, any suggestions
or more data I can provide? The modprobe-produced info from dmesg is
at the end of this message.
Thanks,
Eric

Eric,
When you use the scan command to scan for QAM channels, you must
specify -a2, to signify that you are scanning digital cable.
Try that -- does that work?

Sorry, forgot to include that I'd tried -A {1,2,3} also:

Is THAT what you're doing to scan ?
It looks like what you were doing was scan a tuned frequency for pids.
If you want to do THAT, then you must actually be tuned to the given
frequency. you need to azap SOME_CHANNEL -r, and keep that running
before attempting to run 'scan -c' ... I think you should try the scan
command that I mentioned above.
HTH,
Mike

I was only using one -v, but the scan file isn't the problem. It is
just the single line out of /usr/share/doc/dvb-utils/examples/scan/
atsc/us-Cable-Standard-center-frequencies-QAM256 corresponding to a
known good frequency. Otherwise it scans from 0-70 which are all NTSC
and gets annoying on repeated attempts...
Adding two more -v's doesn't change anything, status is always 0x00
and nothing gets written to STDOUT (channels.conf)
