Video won't playback after upgrade to 0.27

Description
After upgrading to 0.27-fixes today (latest RC - v0.27-RC1-47-g783944e), I'm no longer able to playback any video.
When I launch a video or recording (I've tried several different video formats) I get a "Please Wait..." dialog over the menu screen, and nothing else - it just hangs. Occasionally, I'll get a very small blip of audio. The last thing that just repeats over and over at the end of mythfrontend -v playback is:
Decoder mythplayer.cpp:3319 (DecoderGetFrame) - Player(0): Decoder timed out waiting for free video buffers.
Attached is one of my logs with mythfrontend -v playback. I've tried vdpau and ffmpeg standard xv-blit decoding, same results. I've also tried multiple deinterlacers, as well as interlaced and progressive content.
I also tried the version of the nvidia driver that had worked for months on 0.26-fixes as well as upgrading to the latest version of the nvidia driver.

To anyone affected by this issue, for now you can work around it by disabling Interactive TV (MHEG). We are very close to a fix but as no dev can reproduce currently progress has been slowed right down.

As requested in IRC, a backtrace is now attached for version: v0.27-RC1-47-g783944e. I hit ctrl-C during the hang.
Also, if it helps, I'm running:
- Ubuntu 12.10 server (not mythbuntu)
- Stock 3.5.0-40-generic kernel
- nvidia driver version 325.15 (and 313.30 originally). Installed from their installer script. OpenGL works fine from various tests.

Sorry - to clarify - OpenGL works fine outside of MythTV from various tests. Video Playback did fail with any renderer (Xv, VDPAU, and OpenGL).

There does appear to be a driver problem here, I suspect it's not installed or configured properly. Log shows "OpenGL: OpenGL is using software rendering" at which point it falls back to using the QT painter.
Can you add the driver versions tried and the output of "nvidia-settings -g" to the ticket? Which distro and version are you using? Is the nvidia driver installed from packages or using their installer?
