Decklink SDI file support

I´ve got a decklink sdi installed on my win7 computer. Capturing files and then play them in media express works fine, but i´m not able to import files for playback. I´ve tried ProRes 422, ProRes 444 and h.264 files but none of the will work, just getting a message that they are not compatible. According to the manual Decklink SDI should be compatible with Apple Prores but in my case it doesn´t seem to work.
I also tried to use a h.264 file captured with BMD h264 Pro Recorder but that wont work.
Can somebody please tell me what I´m doing wrong?

Figured out that quicktime with dvcpro codec works...
