Posting a follow-up, in case anyone else runs across this problem.

The SMK transceiver that came with the WinTV-PVR-USB2 MCE kit that I 
recently purchased has a product Id that did not match either of the 
other 2 SMK products included in the list "known" to the mceusb2 driver. 
  Once I added an additional line with the correct product ID (0x0334) 
to the appropriate entries in lirc_mceusb2.c and lirc_mceusb2.mod.c, 
recompiled, and reinstalled, all is working as it should.

As for the missing keys using the Streamzap remote, that was a case of 
user error -- I did not restart lircd after putting the 
streamzap-appropriate lircd.conf in place...

Thanks to the users of this list, who gave me both hope and several 
leads to chase down... Now I can use either remote on this system.
