Revert back to windows media 9. I also had trouble with media player 10. It wouldn't recognize some formats and it would not pick up my mp3 player. I followed some advice i received here and i went back to using media player 9 and have had no problems so far.
WMP10 seems to be full of holes, it was loaded on one of my machines, then while playing a CD crashed the system, upon reboot WMP10 disappeared, and wont allow me to reinstall it! ive tried to reinstall WMP9 and that wont instal either! good job im set to reinstall windows for another reason anyway! my advice stick with WMP9
I responded to Blacki click here post, as I was finding that Media 10 was causing problems that Media 9 had coped quite well with.Possibly needs some 'independent' tweaking to make the new version work to a satisfactory conclusion.
One strange thing that I have noticed, the identification of the cd in motion, gave no details [it couldn't find them!]. Now it seems to have sorted out the problem all by its own resources, even though it displays the wrong cd cover face.
I was going to change back to version 9, but I now think that version 10 will remain for the time being.With a possible few tweaks added.
