I experience the same problem.
I can watch a movie for about 30 min, then problem starts.
Wii MC will start buffering. The buffering will accure every minute. And ultimately the movie will freeze.
I noticed the connection to the Wii seems to slowdown and drop. Sometimes the connection restores and some times it completly freezes. When the movie continues, the problem wil come back every few minutes. (At this point i give up watching the movie this way).
I use a wireless connection. I tested the connection to my Wii. (simultaneously sending a ping to my Wii (and to my laptop next to the Wii) from a 3rd computer).
The ping to the Wii shows packet loss, but not to the laptop. So the signal strenght is not a problem.
I use wii 3.4 and iso38. I did not have this problem with earlier versions of WIIMC.
Any suggestions how to fix this problem?
