hey im trying to use premiere 6.5 to convert some xvid tv episodes i have to dvd. i can play the episodes fine in media player. when i open them in premiere i can play then from start to finish, but if i move the slider bar, it locks up. so when i try to convert them to avi, or to dvd mpg like i want, it starts converting then immediatly locks up. i have tried different xvid codecs with no success. any ideas?
