Whoops!! Not good news re Windows Media Player 10, reported by Neowin today:
I’ve been running MP10 for the past few days, not encountered any issues. But I tend to use it mostly for playing radio station music (current favourite – Choice Radio Classical) and CDs I’ve ripped to my PC. The only niggle I have (so far) is that navigating the program to find radio stations is not as clear as with Media Player 9. I expect I’ll get used to it.
