Problems porting pluing from linux to xbox

[obmib]

Hi,

I have customised the anijunkie-script for a german Streaming-Page. The plugin works for the xbmc-linux-version, but when I try to enter the directorys on my xbox, nothing is listed in there.
Can someone figure out what's wrong with my plugin?

Thank you, and sorry for my bad english.
