using WWW to load ogv onto MovieTexture (winStore)

im trying to load a ogv video from Application.dataPath using the WWW functions onto a MovieTexture

WWW texToLoad = new WWW("file://" + Application.dataPath + "/Videos/video.ogv");

afterwards texToLoad.error contains "Operation has failed with error 0x80004005: Unspecified error" which dosent really contains any usable information

i offcause made sure that the video is placed in \bin\x86\Debug\AppX\Data\Videos\

this works fine on a normal pc build, but not on a Windows Store build
