What they are doing is most likely not, technically, scrambling. They 
are converting the signals to a different format (switched digital 
video, or SDV) which requires different hardware to view them. This 
technicality is one that has been used by lots of cable companies in 
recent months as a way of increasing revenue (by getting you to rent a 
DTA), while also allowing them to offer more channels using the same 
size "pipe".

The Prime can receive SDV signals. My understanding is that if the 
stations you are trying to tune are truly in the clear and not flagged 
as "copy once" or "copy never", then you will be able to see them even 
without a CableCARD.

IMHO, it's unlikely that the same station is going to work any better 
when using a DTA vs. not. If it's truly clear QAM, then a DTA (or Prime) 
will fail the same as your current setup. Any QAM tuner should work, and 
when it doesn't there's a problem somewhere.

But, if what the person on the phone is hinting at (the conversion of 
everything to SDV) comes true, then it's a moot point: you'll need a 
Prime at some point anyway.
