I have many avi files on my laptop and i want to connect to my xbox 360 and watch them through the ethernet cable.

I dont have an external hard droive or any USB to use and i need to be connected to live to get the update for these media files.

i cant do this because i am using an ethernet cable to connect with the xbox and share media and my laptop only has one ethernet port like all others.

I have wireless usb but i cant use on 360 because for some reason it is not recognising it. Is there a way to get this update somehow with my problem?

Thanks and sorry for my English. Dont really have alot of time. Thanks
