So for Christmas, I got an Xbox 360. We use it for playing games, but we also use it for streaming videos/movies from my boyfriend's computer. It recognizes his computer, we can go to his video folder and stream certain videos, but sometimes when we download new movies, it won't recognize them, even after they are shared and we restart everything. The weird part is they are the same format as some that work: avi, and often, the Xbox will recognize them and stream them AFTER we've watched them on the computer. This is minorly frustrating- is there something we should be doing to make it read all avi files? Is there a difference in format from avi to avi? Any help at all is appreciated. The Xbox360 in question is a Xbox360 slim, 250gb hard drive, I believe everything is wirelessly connected to the network- the computer is a home built 2 year old computer. Any other information you need I will gladly provide.
