The 1080p examples that work outside of X.Org run very smoothly on my Pi, but within X.Org they don't run very smoothly at all at the moment.
Given that X.Org is currently not GPU-accelerated, this is understandable - but with the hardware limitations will running such video smoothly in X.Org ever be possible, or is this unlikely even if X.Org was running on the GPU?
X
andx.org
are not the same thing, by the way. X.org is the foundation that owns license on X. In fact, they specifically request only these names be used:X
,X Window System
,X Version 11
,X Window System, Version 11
,X11
