I have a FusionHDTV Dual Digital 2, with a Zarlink ZL10353 frontend that 
performs without problem (aside from an offset adjustment for some 
channels) in Melbourne AU.  So, doesn't seem like we're on  the right 
track.  Can I provide you any data that might be helpful?  As I posted 
earlier, I will have access to a v4 card shortly, so might be able to 
provide some more info then.
