It should work with the Openpli 4 and DM oe 2.0 official images. Other images may need some software which is available from server. Atdee.Net uses rtmp streams - so rtmp support will be needed.
Included in the plugin new versions of Movies25, Icefilms.
This plugin does not require XBMCAddons. But if XBMCAddons is is already installed - install the ipk with option --force-overwrite.
Obviously not all stream sources work - so find the ones that work.
Enjoy and best wishes !
