Vuze not streaming 1080p video

[Rooshkins]

When using Vuze as my media server to watch video on my Panasonic viera I can no longer stream 1080p content. 720 video is fine. The 1080 files are no bigger than 2-3gb and the connection is wired but I now just get the buffer sign on the tv & they no longer play.
Any suggestions ? Cheers in advance.

Are you converting the 1080 files?  If not try it!

Are the 1080 files the same video format as the 720 (like is one mp4 and the other is wmv or whatever?) that could explain the difficulty you are having!
