New owner of an Xbox Live Arcade games along with the rest of the data from your old
Even more upsetting is that the DRM woes aren't exclusive to Xbox Live Arcade games. It seems that any movie or TV episode you've downloaded and transferred is susceptible to viewing limitations. In order to watch a television show, you must also be connected to Xbox Live in order to verify your identity. Microsoft is now recommending against performing a data transfer should you ever desire to view your shows offline.
As far as movies are concerned, all hope is lost. Any movie transferred using the kit cannot be viewed at all off the new hard drive. And what was Microsoft's actual solution to this issue? Watch your movies before you transfer your data.
