(For these who dont know me: I was here since the 8ers are out and have had a bunch of projectes )
Whatever i would like to discribe you my own way to get the Cinema Plugin for free besides Urukdroid.
1) Go to the Rescovery Menu -> Update Firmware
2) Download the Firmware Version 2.3.26
3) Plugin your Archos via USB and copy the aos file
4) Press the Power Button to install the firmware.
5) Install Urukdroid the "normal" way !
How this works?
This trick works because in the firmware Version 2.3.26 Archos has missed to put in the "Lock" for HD/DTS/etc.
Now you can use Urukdroid for the normal use and if you want to see a film you just Boot the Archos into "Android" (The normal Archos Firmware) by pressing the Volume Down Button and selecting "Android".
