W00t!!!!!!!!! i just figured it out, it was because of the firmware upgrade that apple did to version 1.1. it fucks everything up for the 60gb ipod only, not the 30. it accidentaly creates a problem that makes the ipod skip when trying to play videos around 100mb or higher. you simply have to downgrade the firmware to version 1.0. if anyone is having the same problem and needs me to help them, just let me know.
