Thank you for posting that link.  I saw that discussion thread, but
wasn't sure whether or not it was the right one.

Using that patch, I was able to rebuild the mesa package for my
distro (centos6, using elrepo-testing repository).  I only tested
briefly, but so far my experience is the same as what you originally
posted: defect-free, smooth playback (as far as I can tell anyway).

How long have you been running with this setup?  I've only been
testing SNB in general for a couple days, and only got the mesa
patch going about an hour ago.  But I am very encouraged by what
I've seen and your report.  I've been waiting for SNB graphics on
Linux to "just work" for quite a while now.  If I ignore the need to
patch and rebuild mesa, looks like we might be there.

I'm keeping my fingers crossed that, going forward, everything
continues to work as well as my nvidia/vdpau-based frontend!

Thanks again!
