Not sure if you all are aware but the MCE extender software thats actually installed on your MCE pc is the same in both Xbox and Extender packages. what does this mean ? If you Own 2 xbox or wouldnt mind buying another then you can have an extra extender for free as long as your Xbox is modded of course. The Xbox extender software checks for the DVD dongle when loading if it is not present then you can't access the software the DVD xbox dongle works with the MCE extender software and the remote. If you have no DVD remote then you will have to transfer your dongle and remote to the other xbox each time you want to use it. You simply add the extra xbox via your PC 1st then job done.
