World Edition II and Boxee Box

Just got a new 6TB World Edition II. Had a previous 2TB World Edition.

Boxee Box sees the volume just fine and see all the files, but is having trouble with buffering (has to re-buffer every 15 seconds), with recognizing some files as full files (sees only ~60 MB on a 2 GB file). 

The same setup worked perfectly with the previous 2TB World Edition. 

Help?

I think it’s something physical, the 6TB MBWII uses 4K drives (4096b Advanced Format) instead of the regular 512b drives of the 2TB. If that’s the case then nothing can be done.
