That's an understatement.  :-)

My speculation too.  I don't know where that number comes from; the same 
app works fine with the saa7115 driver if I switch frame grabbers.  I'll 
have to do some fiddling with the code to figure out where the problem 
lies.  It's some interaction between the app and the cx231xx driver.

The requested buffer size is the result of multiplying max_pkt_size * 
max_packets and the rejected config shows a max_packet_size of 0, maybe 
ithere;'s a problem with either endianness or int size... ???  Something 
to follow up on.
