[PROBLEM] BSOD when playing large files

[DuffMcShank]

When I try to start playing large files on my RPI Model B 256MB RAM, typically 10GB+, I end up getting a Black Screen of Death after waiting for a minute or so.
I use HaneWin NFS in Windows 8 pro, after experiencing SMB being too slow to cope with large files.
My RPI is connected to a cabled Gigabit network, directly to the router.

Xbian version: 1.0a5
XBMC version: 12.0 Git:20130127-fb595f2 (Compiled Jan 30 2013)

System is not overclocked.

Power supply rating 1250 mAH, also tried several different ones.

No devices connected to the USB ports of the RPi, although I have tried that, but it ended up being able to play even fewer files for me than the NFS network setup.

Both RPi and video source PC connected to the network through LAN.

SD Card: 8GB Verbatim class 10, checked it was listed as compatible before buying
