[linux-dvb] Nova-S-Plus Locking Issues

I have been fiddling with this set up for some time.
I have a Nova-S-Plus in a P4 1.7 running Fedora Core 6

When i first got it running everythign worked great.  Tried it with 1 lnb.
Got Good Signal, Good Locks and channels Scanned.
The kernel that comes with Fedora Core 6 is 2.6.18-1.2798

Apperntly there are problems with diseqc, so i decided before moving to a
deseqc i shouls try upgradeing the kernel.
I tried pulling linux tv hg but it would not compile under that kernel.

I updated to kernel 2.6.20-1.2948 from the repositories. I noticed after
this kernel was loaded that my card would no longer lock. I saw that the
Signal had fallen, previously grater then ff00 now at 6800 and less.I also
noticed the quality was irratic.
When downgrading to 2.6.18 i found the card would once again lock.

Fianlly i tried upgrading and pulling the latest HG drivers, but found
myself in the same position.  Can some one please shine some light on this.
