[quote user="Viral Cyrix"]well it might be possible for your friend to download the content on your console via his profile and put it onto a usb stick.that might work[/quote]That's wont work either. The console license, the thing which would let the Update
be used offline, would belong to the OPs console and not his friend's.
Unless his friend gets broadband the only solution is for him to bring his entire console around to the OPs house or re-encode the video to a format the 360 natively understands.
Another solution would be to stream the content from his PC by means of a program like PS3 Media Server.
At the moment he is getting my brothers PS3 to watch the video and it is going back and forward between their houses about three times a week, so bringing his console to mine once would be better. I will let him know the options. Cheers for the help.
