 Problem is i can no longer ESTABLISH a lock at all.  It simply stays at status 01!
  
 I know ther ewere some Voltage problems with the cards, but it will not lock H or V at all.  Any way to what is going on?!?!!?

The existing 103g which has been in the kernel for a while, is getting the same problem that you are experiencing.  It keeps losing the lock while scanning for channels.  

Must be a patch that was pushed to the kernel v4l/dvb tree.  Been smashing my head against the wall (4 days) until about an hour ago when I started playing around with the 103g card and getting the same issue.
 
I'm running knoppmyth with kernel 2.6.18 with v4l/dvb updates from the 2.6.22 kernel.  The other box is running 2.6.24-0.123.rc6.fc9 with today v4l/dvb tree from HG.

Finds the satellites, locks, scan loses lock.

   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.
