Hi again - sorry I should have searched and seen chris pascoe's post about more data. I've replied to him seperately.
So in the meantime I decided to do some tinkering, and install gentoo AMD64 on my machine. Using linux-2.6.17.6 vanilla again, I get this crash logged in my dmesg:
I'm not sure why it can't find the frontend (I've configured it to build all available frontends), but the callstack of the driver crash is interesting(!)
Cheers
Daniel

Hi there,I have the aforementioned board installed on a gentoo system, using the vanilla 2.6.17.6 sources. In case you don't know, its a PCI+USB combo board and it is connected to my motherboard via an internal USB connector.I've managed to finally get all the drivers recognisning my board, but dvbscan moans at me (using both -a0 and -a1) with:MediaPC dvb-t # dvbscan uk-CrystalPalace

I thought it might have been a range thing, so i found a definition of a transmitter about 2 miles away:MediaPC dvb-t # cat uk-Guildford

I'm completely at a loss. Before trying the board out under linux, I used the vista beta media center and that did find the channels alright (but I plan on using MythTV).I would really appreciate any help you could give me!ThanksDaniel
