There's just a single CY7C68013 but two CX23416's and two CX25840's?

This sounds like it should work, except for the bit about a single FX2 
(the CY7C68013) driving two video pipelines.  The normal firmware in 
that chip only expects to talk to a single tuner, not two.  That may 
cause a hiccup with the pvrusb2 driver since it was never designed with 
a configuration like that.  Otherwise all the chips you've identified 
are workable - in fact ignoring the dual pipeline setup this appears 
very similar to a Hauppauge 24xxx device.

Odds are pretty good that you should see an I2C EEPROM on the board.  
It might be a very tiny chip (perhaps an 8 pin SMT part).  Knowing its 
ID will tell us its capacity and from that we can probably guess whether 
or not the FX2 firmware has to be loaded from the host.  (The pvrusb2 
driver can handle it either way but we have to know.)

Having a hi-res photo of the whole board is where things like the 
question about the I2C EEPROM can come in handy.  That would give a 
means to go back and examine it for parts missed on the first pass.

Sorry about the reply delay; it's been a busy week here and I've been 
distracted on a different project.  Now off to handle a pvrusb2 e-mail 
backlog...
