Music CD's on DVD problems

noodles (30-12-2000 13:28):
Got a new Sony DAV S300 DVD player - plays proper music cd's but won't recognise downloded music off of napster etc which are recorded onto cdr's (kodak, infiniti etc) Writer is a scci Yamaha, discs work perfect on home hifi and car etc but wont on dvd please help.
Dvd is not multi-regional.

Try different cdr's once it will work, i have the same dvd and i use "thats right" cdr's and they do play normal..
