Permissions EXT4 drive, XBMC cannot access folders

[zilexa]

I have a new harddisk, formatted as EXT4. I transferred all my media from an NTFS drive to the EXT4 drive using Ubuntu from an USB stick on my Macbook.

I used rsync command from a Terminal logged in as root on Ubuntu, copying 2 folders: Movies and TV Shows. All other folders (Pictures, Music) were already present on the harddisk.

The problem: in XBMC, I cannot open the two folders Movies and TV Shows. I tried various chmod commands:

sudo chown -R xbian:xbian /media/usb0
sudo find /media/usb0 -type d -exec chmod 755 {} +
sudo find /media/usb0 -type f -exec chmod 644 {} +

No errors but nothing changed. I want to be able to read and also delete files from within XBMC.. just like I used to on my old ext4 drive.. I Googled other commands but I don't understand why nothing changes?
