dmesg output

Whenever I try playing a h264 encoded movie, the system/X11 locks up completely with 3 different symptoms.
X freezes, I might be able to move the mousecursor (which doesn't change), was able to log in to the machine remotely and reboot it.
X freezes first, full screen is garbled just a few seconds later.
Additionally I might be able to move some square, which is likely the "cursor".. garbled as well. I must be honest I didn't try logging in remotely there yet, if the machine itself is still alive.

Machie is running:
Linux 3.15.4 from the repo and tried on a 3.16rc4 today (Installed that to test against a kernel bug)
Xorg is 1.15.2
mesa is 10.2.3
mplayer is SVN-r37224

I tried a mpeg2 video and played it just fine
( mplayer -vo vdpau -vc ffmpeg12vdpau <file> )
I also got two h264 files and it freezes/garbles every time there

http://samples.mplayerhq.hu/V-codecs/h264/PAFF/Grey.ts
http://samples.mplayerhq.hu/V-codecs/h264/nature_704x576_25Hz_1500kbits.h264
mplayer -vo vdpau -vc ffh264vdpau <file>

It reliably just freezes the screen, with the mouse working for a while or completely garbles it.
I also had an occurrence of the screen going garbled and then black, back to the garbled screen. Three times or something. Maybe he tried resetting the GPU or something; I don't know. Not sure if I can find any logs from that one.

Also: Haven't tried any other codecs yet, that might be supported.

Oh, also.. nothing about that can be found in the Xorg logfile.
And I'll try to gather some output from mplayer from when the screen freezes, if there will be anything, when I got some spare time later and feel like crashing my xorg again

Late answer, but mplayer doesn't give any output.
And I'm wondering if it could be related to Bug 71923
