I created a new profile group for experimentation and it only has one 
ruleset which has  rez > 0 0. I then modify the decoder setting and the 
video render setting within the offered choices. I then try out the 
change to see the affect on cpu usage, etc. I haven't figured out which 
specific setting(s) causes the xvmc to stop working but it is repeatable 
that deleteing all the  profiles clears the problem.

Given that the profile settings for video decoder and deinterlacing are 
constrained by the choices of decoder and assuming that these 
constraints are compatible, what possible misconfigurations would be 
likely? Incompatibility with the hardware capabilities?

Thanks
