I have recently burnt a few audio cd's using nero 7 and when i try to play them in my HI-FI they dont work, but they do play in my dvd player
I also had a friend try burning them as they use nero 6 and they worked in ht e HI-FI without any problems, could this be a software problem or a media problem, any thoughts on this would be greatly appreciated

Hmmm...I had this problem in the past and it turned out that my Technics Hi-Fi just wasn't compatible with burned CD's.

see now i thought of that too, but i have played cdr's in it before, so there must be something else, i just cant think what it might be
