Sadly, I am new to the MD arena. I have read lots of posts, did some(not alot of research) and purchased a few MD players. I got some blank discs, some pre-recorded discs and for the most part enjoy MD! Here is my dilema. I record something on my Sony MDS-JE510 from a CD and it works fine. Plays back prefectly and I named it. However, when I try and use it in my vehicle (using Alpine MDA-5048) I can't get anything but errors. I know the Unit is working, because it plays Pre-recorded MD's great! Am I doing something wrong? Does it require me to do anything after I record the CD to be played in the vehicle? Truely frustrated! Any help would be greatly appreciated. One last question, where might I "buy" pre-recorded MD's other than rip-off central(Ebay)? Thanks in advance, Jim
