Thanks to everybody that replied.

I have been using the mencoder man pages as a reference where an example is 

       Encoding from a pipe
              rar p test-SVCD.rar  |  mencoder  -ovc  divx4  -di-
              vx4opts br=800 -ofps 24 -

       Encoding multiple *.vob files
              cat *.vob | mencoder <options> -

I have also been using the "DVD ripping and transcoding with Linux". It also 
shows using a pipe incorrectly, according to this information.

Are there any definative guides thisgroup can recommend for ripping, encoding  
and playing?

Thanks again to everybody and especially the coders who have made MPlayer what 
it is - your efforts are truly appreciated.

Best regards,
