Likewise- I have a WD 640Gb Passport split almost in half with WBFS Primary partition and NTFS additional partion.
Loads, looks groovy but won’t play video files- .avi format, have not tried music. I get a code dump- black screen numbers etc.
MPlayer CE works but since the last time I updated it it also gives the code dump at the end of playing a file or when you quit from it. The update resolved a temporary hang situation which took minutes to open directories. I’m not sure if this has any bearing but thought the more clues the better.
Good luck with your project, it looks very promising. Thanks for sharing.
