About a week or so ago I installed this mp3 add-on converter. I had some CD R's that had been laying around for a year or so and decided to burn some music CD's. The converter worked great. I was able to play them on my computer and in the car. Last week I went and bought a ten pack of the same CD's and burned 4 more discs only to discover that they would only play on the computer but nor in car. Thinking something might be screwy with the discs I bought another pack from a different mfg. only to get the same result-won't play in car. This has me really annoyed. I see no reason why these newer discs will only play on computer and not in the car. Anyone ever have this problem and if so was there a way to fix it? Thanks
