In web admin you go to orbiters section and tou chose to add an Onscreen orbiter and then you select the room you want to add and this way you will create and orbiter for your core.

At the moment there is no way to uninstall LMCE from your Edge but maybe in the next versions this feature will be implemented.

What kind of problems do you have? please make a list or something and if you have issues try to contact the guys from the support http://wiki.linuxmce.com/index.php/Tech_Support I hope they can help you.

Yes you can do that using Linux MCE and yes you can connect it to the core or media director and you need to connect it after the cable box.

You can install linux MCE and then you can do the setup for myth tv

What kind of installation have you made? Do you have a dedicated core? and on Ati ui1 will work and ui2 with alpha blended works ok on 6xxx series.

Here is a wiki page with a guide for installation http://wiki.linuxmce.com/index.php/Installation_Guide  and after that you can check

What kind of installation have you made? Your core is dedicated?

After you will insert your hdd with media and after that you boot up the system a message will appear asking you to add a Generic Internal Drive which is you media hdd and if you choose "yes" and add the hdd after a Quick reload Router you will see you media from your hdd on Linux MCE. Good luck!

I think 512 mb will do the job but 1G would be great and you will have no  troubles, here is a link to wiki http://wiki.linuxmce.com/index.php/What_hardware_I_will_need#Standard
Hope this helps.

Check the wiki maybe this could help you http://wiki.linuxmce.com/index.php/Installation_Guide

If you have a s60 phone it is very simple you must turn on the bluetooth connection from the mobile phone and you will see a message on onscreen orbiter asking you if you want to add that bluetooth device. If you choose "yes" a you will receive the app on your mobile phone.

That is pretty weird can you give more details? When you add a MD you supose to turn on the pc you use as a MD and on the onscreen orbiter from the hybrid you should receive a message asking you if you want to add it or not.

Usually when ui2 it`s not working there is a message "Orbiter failed to setup transparency" and then you must change to ui1 (static images)

How did you PVR work?
