I'm still having problems.  I downloaded and ran 4 live cd distros
(mythbuntu, slax, nimblex, kanotix) and all 4 were able to pull video
from the DViCO card with NO problems.  As far as I can tell, the dvb
drivers are the same in those 4 and FC9.  Was there any change in DVB
drivers between 2.6.24 (that the live cd distros I tried all run) and
2.6.25 (that FC9 uses)?  Anyone out there that uses this combination
(DViCO Fusion 5 Lite + FC9)?  Or any 2.6.25 kernel?

Thanks!
