I am using XP home on my Compaq SR1710. My problem is with playback of CD's made on my computer. I can play any commercial CD but not those which I burned on this machine. I can take any of the "homemade" CDs and play them on my home system, or in my car, but NOT on the computer. I used to be able to play them on this computer but at some point, for some reason I cannot now. HELP PLEASE!!
