I have pinnacle studio 9 and have made 2/3 smooth and successful dvd's. The past few movies i have created have played back perfectly during the editing process but but when i burn them to dvd and play them back through the dvd recorder/tele, anything over 20mins starts to jump or freeze for a second or two, this repeats more and more towards the end of the movie. I have a 6 month old machine with 3.0Ghz processor and 1064Mb RAM. Does anybody know of a solution??
