Please try the latest CVS version of the driver. I just checked in a
new firmware which should now do auto switching between PAL and NTSC.
I tested it with 2 NTSC channels (thanks to the people who told me
where to look for them) and zapping between them and PAL channels
works fine. I tested it on version 1.3 and version 2.1 cards. 

Btw., how did you try to switch to NTSC before?
The option for the SAA7146 driver will only affect output via overlay.
But without setting the AV7110 to the right mode you will get no
picture at all (not over composite or overlay) anyway.


Now somebody tell me where I can find channels with spectral inversion
in Europe and I'll take a look at that next.
