Haven't looked at BER values and such, but I can confirm that my single 
Budget Nova-S system is working ok when I boot the non-udev gentoo-2.6.9 
with the kernel-supplied drivers and vdr-1.3.14, and not working at all, 
when booting the fresh installed udev-enbled Gentoo-2.6.10 with the 
kernel-supplied drivers, and I tried all this FU weekend vdr-1.3.21 back 
to -20, -18 and -14 on this partition, with no results.
I also asked for help in just some pointers where to look for the error 
in http://www.linuxtv.org/pipermail/vdr/2005-February/000171.html bot I 
only got a suggestion from Darren Salt in this other thread Tony 
initiated. what do you think I could try? disable udev and go back to 
devfs? Downgrade the kernel? Use DVB-CVS drivers?
the funny thing is that dvbscan is properly scanning for services at any 
of the 4 LNBs I have after the 4/1 DiseqC switch, and even dvbtune 
reports something like this, how does it look like? Any other clues?
