Since I am using a parallel programmer, and I already used it with 
AEC ISP software to program AT89S8252, I am sure it works fine (it 
just a cable that connects MISO, MOSI, SCK, RST and GND to the 
parallel port).
I checked continuity from the DB25 connector to the ATmega16 
programming pins, and everything is ok.  Also, I verified the power 
(5V).
I will check again the board circuit and the parallel port 
configuration.

Regards,
Jose

Maybe also your reset pin since the programmer needs to pull reset 
to ground for 20ms.
