My 8gb card runs fine . It yours a class 2 or class 4 ( It will have a C with a number in it on the card).
It might be something with your phone as well.
Did you just sideload them through WindowsExplorer or did you use the Sprint media manager to do the converting. It could be the Files you have have a different setting then the Instinct needs
Mine is a class 4. I use the software that came with the phone. How did you do it?
I have done mine both ways and don't have any issues . I have no other answers or suggestions. Maybe call CS and see if they have anything.
If you hook your Phone up to the Computer and use WindowsEX click on a Video from there . See if it skips on the Computer as well if not it must be something in the Phone not keeping up.
