Large video's not playing correctly, layout errors

I'm having issues with playing .wmv video's:
When I schedule a small video (~1mb, 00:10) to play Xibo does it fine, but when I select a larger video (~80mb, 07:00) the layout loads for a sec (and shows layout) and then reverts to the default Xibo splash screen and doesn't go back to the scheduled layout. Only thing I know is that it doesn't add the video to the client library, but the video does seem to upload properly to the CMS; I get no errors and it shows in the CMS's library.

I read several topics about the layout reverting to the default Xibo splash screen when the content (layout) is invalid, but that didn't get me any further. Everything works without the larger video in the layout. Also, I just found out this problem also occurs when I put a website in a region.

Video information (from VLC):
Codec: Windows Media Video 9 (WMV3)
Resolution: 1352x760
FPS: 25
Decoded format: Planar 4:2:0 YUV

Any help would be greatly appreciated.

Error log:

I've opened the log and for my last run (client gets stuck alot on errors) it states that both video's have downloaded 100% but the bigger video isn't playable in the library and still makes the layout invalid. Here is the error log:
