I've noticed towards the end of a movie when I hit pause an error message immediately pops up saying something like the codec cannot be played. When un-paused the error message goes away and the movie continues playing with a blue spinning wheel in the middle of the screen that never goes away. Two other things I have noticed is that when I power up my PC the WDTV live cannot be seen on the network and the WDTV live cannot be powered off. Sounds almost like a hardware problem that occurs when its warm and has been on for a while. It is well ventilated.
