I have a 360 I'm using as a WMC extender (I have a HTPC with a Ceton card, and it streams live TV and my DVD library to the 360 in another room over my LAN). I was thinking about getting it setup with a Coolrunner so I could play backups off of a USB drive. I know I can't get on Live, but will it have any negative effects from being on my LAN to stream the HTPC? On a side note, I remember when I first got it it did a search and downloaded some codecs to play video files. Hasn't happened again in months. But if it does ask to download codecs, would that get me banned? Thanks for any info!
