I didn't mention the DCR-2650, because I thought it was not supported.
 Apparently, I was wrong.  I would say it is worth it as it will pay for
itself in under a year if it replaces one cable box rental @ $10/month.
 Twice as fast if you consider the fact that it has two tuners.  On top of
that, you do not have to pay to replace you PVR150.  Even if CC goes belly
up in a year, you are in the black.

The thing that you really need to worry about is not encryption, but rather
copy protection.  The cable box and CC does the decryption.  Firewire copy
protection is technically different than CC copy protection, but you will
find that, as a general rule, you will be able to get the same channels
with both methods.  There are some exceptions that you hear about from
time-to-time, but they are rare.  It primarily depends on your provider.
 The big thing is that the CC solutions are much more stable in my
experience and can pay for themselves in the long run.
