Thanks for the reply Mike.

I thought my particular set up might be quite rare, especially using
a combination of vdpau and xv-blit. It certainly works fine if I
use vdpau throughout.

I've attached the output of the mysql query. The frontend in question
is called lithe. I don't have xdpyinfo on that machine. It's minimyth
based so I cannot install it either. Is there any other way to get the
information you requested - perhaps the X log?
