Re: Fwd: [Xen-users] mythbackend dvb cards...need some guidance...

[Mark Williamson <mark.williamson@xxxxxxxxxxxx>]

Do you have the kernel / modules for the DVB adaptor installed in your domU?  
The easiest way to get this is probably to make sure its the same kernel / 
modules as the dom0 instance is using.

Did the DVB adaptor work correctly from dom0?

Can you post the dmesg output from booting the domU with the adaptor attached?  
And the dmesg output from dom0?

Cheers,
Mark
