It's bigger cousin, the PCI-hosted HVR-1600 does have a hardware encoder
for the analog side. However that encoder probably takes too much power
and is too large to work in a device like the tiny HVR-950. This is
probably why it lacks a hardware encoder.
Now, there are some other hybrid USB devices out there which also do
hardware encoding. But they're not from Hauppauge and not anywhere near
as commonplace. Two devices I know of are of a size similar to the PVR
USB2 and both require external power.

Nice thought. But I don't think or expect that there's anything like
that in the works.

The encoder chip was not created by Hauppauge. They purchase and
include it in their product, same as a number of other vendors. So
Hauppauge probably isn't in a position to even try something like this.
To be able to be flexible with the choice of codec would also imply a
much more complex encoder chip - it already sucks down too much juice to
be USB powered :-(
