Some times i use tmpegenc dvd authoring for author dvd,What is defrend pixel 12:11(4:3) and display 4:3.Before i start to author the dvd which render by svp 11,i must set the aspect ratio.
May be the video file video was corrupted…try to do again the project file and try to render back because i already face this probleum in sv 11.my sv 11 now working very well.
You right MR.MIKE KUJBIDA……i have same probleum but after Mr.John Rofrano adivice me…..i just uninstall the k-lite and reinstall the sv 11, now its working very well.
