> I play around with mencoder for about a week now and really like it. But 
> now mencoder does not work anymore. Maybe some (arpi) can help me out.

> Recently I changes my CPU from iPII-350MHz ro iPIII-700MHz and added 
> some extra memory. The system running SuSE Linux 7.2 is acting well and 
> VDR is also working flawless. 
>   
> Whenever I try to use the old mencoder (compiled with iPII and seems 
> only to use MMX) or a new compiled one (used CVS from today) mencoder 
> always segfaults.  
>   
> I also tried to vary parameters and so on. Now I am going to recompile 
> LAME and MAD.
