So, I'm not sure if this is the right place or not, but i've been hving some serious issues with my video player. I have a laptop and a mac connected up to it via a wireless network, and most movies or shows I watch work fine, however, some do not work properly. The video jumps and pauses, causing the audio to become out of sync. Files have been converted into .avi or MPEG4 and it still happens.The files work perfectly on the computers, but not through the Xbox. What am I doing wrong and how do I stop it?
