MP3 in DVD player

alright i have a Directed DVD player in my car. it can read dvd,vcd,and mp3. now my question is when i put in a mp3 cd it displays the names of the songs but they are all screwy. there is a bunch of question marks in the middle of words and things like that. for example lil~yne which is supposed to be lil wayne but some how the tilde got in there and the wa is gone. now im thinking its the way im burning the cds maybe i have to do a differnt iso format or somethin like that. im using nero to burn them. thanks in advance for any input.
