I bought an itouch from dealextreme to replace an r4. I noticed it skipping right away when I started playing metroid pinball. I though it might be the microsd card so I put it in the r4 and metroid pinball plays fine no skipping at all. So now I'm thinking of buying another card but I don't know if it's all m3 cards that are like this or if it's just a knock off I got from dealextreme. Can anyone else confirm this for me with an itouch and the m3 simply/real? Does metroid pinball play fine no audio video skipping?
