This means no more game updates (aka title updates), XBLA games, marketplace content, netflix/sky player and so on. There is no way around this, all online capabilities are now disabled PERMANENTLY.
Hard Drive installs are now disabled on the banned console. This means any disk-based games you have will no longer play off of the hard drive.
There is no way to fix this, that functionality is simply gone from the banned 360.
Windows Media Centre functionality is disabled. It is still possible to stream video/music content via the video library.
So, in summary:
Your Banned 360:
* Cannot go on Xbox Live
* Cannot install games to the HDD
* Cannot use Windows Media Centre extender
* Cannot be used to get achievements from backups without corrupting your profile
