Just read the docs anyway including docs/design/*.txt. Autoplugging is 
not magic, just use signals to get notified about new pads, check the 
caps and search the registry for compatible elements. Sort the elements 
by rank and ignore those with rank=0.

It might be better in the long run to figure whats the issue with 
playbin2 and vaapi/vdpau and make sure we can fix it in 0.10 or at least 
in 0.11/1.0.
