XBMC Not Installing

Hi,

I have recently purchased a second hand Apple TV 2.

I used Seas0nPass to jailbreak the Apple TV 2 and it automatically uses the Apple TV Software 5.2.1 and i get the Firecore logo for the Settings tab.

However from here I have tried to install XBMC through 1) SSH and also through 2) Nito Installer (for Windows).

For SSH i get an error which reads that "Depends: org.xbmc.xbmc-seatbeltunlock but it is not installable".

For the Nito Installer - it says it has successfully installed XBMC and restarts the Apple TV but there is no XBMC App to select.

I also already have NitoTV App installed through the Nito Installer - but even through there i get the same error message as i get through using SSH.

Please could someone help direct me, as to how to install XBMC.

Thanks.
