Ok I've tried to burn these tracks as they are mp3 (downloaded from the internet)same result, all goes well throughout the burn process, tells me that burn is successful but when I go to play the cd on the computer or home system there is no sound at all, the tracks are there allright, but when I make comparisons to other discs Ive made I find that when I click on the the Audio cd (D) symbol, the other discs I've made the tracks first appear on page with there little wmp box tracks 1 to whatever but not on this lastest attempt it just goes straight to wmp, all tracks are displayed and played but not a sound is heard.I have gone through and checked all the properties and attributes and they seem the same as all previous other discs I've created.Also the downloaded mps tracks and the converted wave sound tracks all play the music on the computer only after trying to burn them do I get no sound and no page displaying them in their wmp box. Ive always done it this way as I dont think my home system recognises mp3, I might be wrong but wav has always worked fine why change? I hope this sheds a little more light on whats going on here, so please if you have any more advice or knowledge on this issue Id really love to here it
