hey guys so im making a pvp Movie for wow - now i took all my footage and rendered it using Sony vegas (to save file space)- i watched the .avi in media player - works perfect - now when i reinsert it into Sony vegas - to add effect and such - i watch the Preview Video and in certain spots the whole screen turns Black. but when i watch it outside Sony Vegas - these Black screens randomly throughout the movie do not exist - Help

PS - i noticed the preview is very jerky also - like it freezes up for a few seconds then jerks forward then slows again - what is up
