Hello!
If I want to play a video with CoreAVC (mainly h.264 encoded) and DXVA enabled which got any kind of subtitle stream MediaPortal crashes with a runtime error. (see attached Screenshot)

Steps to reproduce:
1. Use CoreAVC 2.5.5 and an ATI graphic card and enable DXVA in CoreAVC configuration.
2. Open a video/movie file inside MediaPortal which uses CoreAVC and got subtitle stream(s)
3. MediaPortal crashes

I made some more tests:
CoreAVC + DXVA + ANY subtitles = crash (runtime error)
CoreAVC + DXVA + NO subtitles = working as expected
CoreAVC + DXVA disabled + subtitles = working as expected

I tested this also with my nvidia card in my laptop (GeForce 9600M GT) and there are no problems at all with subtitles in videos no matter if CUDA or DXVA is enabled in the CoreAVC Configuration.

With MediaPortal 1.2.0 ALPHA there were no crashes under the same circumstances.
After the crash I see an error.log (attached)

Thanks!
