One thing I noticed that I don't remember happening with beta 7, but when playing WMAs the audio is choppy if I move through the UI while a song is playing. The choppiness stops as soon as I stop touching the UI. Does not happen with MP3s. Note that I'm using the .26 version of MPlayer. I'm not sure, but I "think" I was using the built-in N800 player with beta 7.
