Although I've run into problems with my WMP and had to roll it back to an earlier version (I now have WMP9), I have no problems burning CDs. I have a CD burner that will burn anything that's suitable for burn. Usually, CD burners will burn WMAs or MP3s depending on how you have it set up. Not all CD burners will burn videos, because not all of them have that capability. I know I don't, since I don't have a DVD-RW.

thanks for your reply...i have wmp 10....problem is , i download say 15 tracks usually mp3 files...when i get to go burn them , i find only 4-5 will burn... the others all have license statements or other error messages...how do i know what to download and that it is going to burn , or play in wmp....i been looking thru the forum, and doing the suggestions , but seems i still have the same problems, ...thanks agian for any further advice ...
