ive seen the reviews and charts and what not to prove that sandisk memory sticks are overall better. but what im not sure about is the ability to play atrac3. i have my sony memory stick which is reconized by sonic stage and plays atrac 3 just fine. but when i went to transfer songs to my friends sandisk card, sonic stage didnt even reconize it. is this just a weird case or it this the same with all sandisk cards?
