This was a upnp-related jump into a different thread - but I'll add a 
couple of comments.

I'm not up-to-date with the Samsung story, but there have been other 
tweaks to the upnp code:  for example, treatment dependent on the 
'transcoded' flag, or resetting the container from 'MPEG2-TS' to 
'MPEG2-PS'.  Most have been for upnp-spec compliance (the spec seems to 
be accessible now) but some hardwares might still need 'features' that 
will break others.

I have three now-cheap core2duo boxes running almost-current master in 3 
OSes; one has a current low-end nVidia card, GP710 driving hdmi.  I find 
upnp playback is noticeably more 'solid' in rapid HD panning scenes than 
I have yet seen from VDPAU, and if I wanted to watch a large(ish)-screen 
'performance', without skipping or speed-up, I would choose upnp.  And I 
can get that from them all.
