First post here... I have an HP Media Center 470n. The DVD-RW, CD-RW is an HP DVD Writer 400c. I have never had a problem burning before. Now, in all programs (Winamp, XP Burning, etc.) I cannot make a CD. It seems that everytime I try, it says that it indeed does complete. However, when I try to play it, it is blank. I have watched Winamp burn a CD and it usually gets to 27% on the first track and then says complete. If I use Windows XP to burn using the Writable CD Folder, it always gets to the end and says 5 sec left. Then it gives an error and the disc is again useless. The only thing I have installed recently is Windows Media Player 10. I have since uninstalled it. Any suggestions? Thanks in advance, Patrick
