I have been using DVD Shrink 3.117 for a long time. Have burned numerous movies without a problem. Recently the last several movies I've burned, the last 2 chapters of the movie will freeze then play a couple frames then freeze so on and on to the end of the movie. I have not changed anything in the way I burn or as far as software added. I do not run other programs while burning. I am using the same DVD+r disks I always have. Ritek 4.7 4X I burn on a Pacifid Digital burner 4X. Does anyone have a suggestion??? This is very frustrating and costly as the dvds are too expensive to just throw away.
