I had this problem with a Nebula DigiTV card, turned out the permission were
wrong.
Have a look at the permissions on the device files, once I change mine Myth
was happy to register it.

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 Linux video capture

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
