This sounds like a bug in X to me - I'm not aware of any code in the 
nv driver that handles aspect ratio.

Did you check the X log files carefully? Maybe your option in 
XF86Config-4 was somehow ignored.

It's possible but rather unlikely.

You can try. In the early days of driver development I commented out 
everything that caused problems and everything that I thought 
wouldn't work on xbox anyway. I'm not sure into which category the 
dcc calls fall. 

I don't think DCC is going to solve your problem, however. There is no 
possibility to connect a DCC capable display and the video encoder 
doesn't care much about any DCC signals.

The modules in xebian were compiled with 4.2.2 sources but the 
binaries also work on 4.3, IIRC. You simply copy the CVS sources over 
the original sources and run "make world". To build nv_drv.o only I 
usually just run "make" in the nv driver directory.
