Ive been using Wiimc to play movies (.avi and mp4 mostly) from an external USB drive. It works fine if there isnt much action on the screen, but when there is it stops every second or two to buffer for a second or two. Painfully annoying. I was using Wiimc 1.1.8 and just installed 1.2.2, same thing. I tried dragon media player 0.25 alpha but it seems to only be playing audio not video. I tried, Mplayer CE but it wont load or even read the USB. Is there a better program to use or is this just a wii limitation?
