I updated to todays cvs, but that makes no difference.
What magic of layer configuration could that be? Below is a code snippet I
use in that case. When use "#if 0" I'll get the signal via composite out
IRQ 16 is used by matroxfb but could not set field parity.
With "#if 1" there is no exception thrown, IRQ 16 is not allocated and
tv stays black :-( .
