Built my Media Centre PC from a Dell Pc I got cheap and have it hidden under my kitchen breakfast bar. Really pleased with it and have it Networked along with my 360 and a laptop. BUT!!!! Tonight I went to watch a Video clip using my 360 as a media extender only to discover that it won't play any of my vids and tells me I need the correct codec. The codecs are installed on my Media Centre Pc and the vids play fine so how am I going to get them to play in my living room through my Xbox? I know I can just recode them using Windows Media Encoder but it's time consuming and why should I? Anyone know a way to get the 360 to either except them or a codec pack?
