I'm relatively new at burning cd's on my pc so forgive the question if it's been asked a zillion times. I did a search and nothing showed up so...here goes. Is there a difference in regards to compatibility in playback if using CD-R's that say DATA CD-R's and use them for music burning? And what's the difference in blank cd's that say for "Computer Writers Only", "Data CD-R's", "CD-R's for Music"????? Reason I ask this is I just burned a pretty cool Star Wars soundtrack compilation cd. I used a TDK 80 min Data CD-R. I used those since I initially got those for movie trailers, pictures etc...Well it plays fine on my pc, dvd player (pioneer 414), but my car cd player has trouble reading it. You can hear it spinning...trying to find the tracks I guess then finally it plays. It took almost 5 minutes to play this afternoon. Once it plays it is ok as long as you don't skip tracks! I don't think I've ever had trouble playing Music CD-R's if my memory is correct. My car is a 1999 model if that helps. Thanks for the patience with reading this thread!
