i really want to know how this is connected or just a coincidence (transcode crashing the same way)

both clips play absolutely fine with Quicksync and some other 3rd Party DXVA Decoder (Arcsoft,Cyberlink) though all based on Laurent Aimars DXVA 2 implementation (VLC) crash with those both on Intel Hardware

The crash happens in ntdll and igdumd most probably a buffer overflow
They work fine using QS like you said.
BTW, the 2nd clip (cuda) is H264 not mpeg2 (avc1 fourcc).
