CD's made in Win 98/ME are showing up as blank cd's in Windoze XP. Not only on my computer but on several others. Not only cd's I burned but from others too. Stick them in a win 98 pc and the data shows up just fine. What gives??

Also, since installing XP, I can't burn CD's. Works fine with 98/ME as I had to go back to my old operating system.  

Thanks.
