for some reason when playing back an mpeg in windows media player it is impossible for me to jump to say half way through the film if i try to skip for ward or backwards during the film it will just freeze cant work it out i have k-lite codec pack installed then i uninstalled that and installed the ffdshow package no joy i just tried in a last ditch effort to upgrade from wmp10 to wmp11(beta) and still no luck its worth mentioning that i can skip through the film using windvd 4 what could be wrong?
