[mythtv-users] DVB-T, Could not open card #0

[David Whyte]

Wow!!!  I think my AverMedia 771 DVB-T card is up and running.  I can
run tzap and get signal locks, but I can't use player to test (even
after trying to recompile with DVB support it just does not seem to
understand the dvb:// argument.

Anyways, everything seems good, with the following output from DMESG

PCI: Setting latency timer of device 0000:00:11.5 to 64

DVB: registering new adapter (bttv0).
DVB: registering frontend 0 (Zarlink MT352 DVB-T)...

The problem is that in Mythsetup, when I try and setup the adaptor, it
obvisouly recognises the card as being there but it cannot open the
card, the 'Device or Resource is busy'.  I am running everything as
root and the ls of the adaptor0 directory is as follows:

[myth at myth myth]$ ls -l /dev/dvb/adapter0/
total 0
crw-rw----  1 root video 212, 1 Nov  4 23:09 audio0
crw-rw----  1 root video 212, 6 Nov  4 23:09 ca0
crw-rw----  1 root video 212, 4 Nov  4 23:09 demux0
crw-rw----  1 root video 212, 5 Nov  4 23:09 dvr0
crw-rw----  1 root video 212, 3 Nov  4 23:09 frontend0
crw-rw----  1 root video 212, 7 Nov  4 23:09 net0
crw-rw----  1 root video 212, 8 Nov  4 23:09 osd0
crw-rw----  1 root video 212, 0 Nov  4 23:09 video0

I don't know what, but in another post i read, the '212' part was
significant, something to do with a change in the major version
number.  Of what I don't know, but by soeone noting that, it fixed the
guys problems.

Anyone have any decent ideas of a way to step forward???

Cheers,
Dave
