[vdr] deleting empty directories on a samba shared drive

I have two samba shared video drives on my vdr system. Everything works great except empty directories are not erased on these drives. They are erased on my Linux drives. I can manually erase directories on these drivers with rmdir under Linux. There does appear to be any permission errors. The error in syslog states the "device or resource is busy". Any ideas on what the conflict is?

I would like to reproduce the exact command that vdr is issuing to erase the empty directories. I traced it to a remove(DirName) command in tools.c I don't see code for the remove function. Where is remove defined?

Thanks for any help!
