Hi All,
(Please excuse the length of this email.)
I have two VisionPlus DVB-T cards based on the TwinHan chipset in a
machine running linux 2.6.10 with a few misc patches.
I've loaded the appropriate drivers, and as such the cards are detected
properly, as shown in dmesg:
Linux video capture interface: v1.00

After a little bit of mucking around with udev's rules and permissions
I've managed to get the devices nodes created properly:
/dev/dvb:

However, I can't seem to get the card to tune in to any stations:
elmo tom # scan -vv -a0 au-lofty
