Hello, I recently purchased a rMBP 15 (high end model) and I'm experiencing some issues while playing movies over WiFi. The movies are 720p and 1080p movies in .mkv format and are stored on my main PC. I'm using VLC player to stream them. The issues I'm having is that the video stutters, hangs, while audio sometimes continues. Sometimes it just stops completely and continues after a few seconds. My other laptop, a 3 year old Intel i3 plays it perfectly. What could be the problem here? Is it the WiFi connection, the rMBP itself? Any tips on how to improve this?
