I have an iP4 that I jailbroke yesterday with redsnow. Today I've tried to watch some video over wifi and they freeze. If I tap on screen the menu controls come up and if I wait a moment and hit play again it seems to "catch up" for a moment and the stops again. I had a Cydia app of Flash installed and have removed it but hasn't helped. Anyone have any other ideas as to why this is happening?
