Thanks by your adaptation.

Sure :-).

Sorry by the delay, as I wasn't using any modern driver, not other VDR that
1.0.4 .

On other PC (K7 @1265MHz) that I was also having an inmediate crash with
VDR and the modified card & drivers, I've instaled the driver snapshot of
30/12/2002 and VDR 1.1.19 .

With the modified driver (your adaptation of my patch), I get an inmediate
crash ('Scheduling in interrupt...' [1]) when VDR start (the image isn't 
show yet, only the OSD).

[1] Could anyone explain this a few more?. Is it some "forbiden" call, wich 
    would imply a dispatch, in the interrupt routine?. Supossedly, the
    SAA7146 interrupts are disabled and the interrupt routine will not be
    reentered; on the old drivers the filtering of the packets is done in 
    the interrupt routine and the crash is exactly the same.

With your interrupt stability patch, the crash is delayed a few minutes (2,
5, 2 on my tests).

After set the PCI Latency to 128, seems that the  system is a few more 
stable (9, 5, 8 minutes to crash), but nothing good anyway :-(.
