I have a friend who doesnt have the internet so I am asking here for him. He says he has a piece that a network wants to use for HD and is requiring him to submit a tarnsport stream with AC3 audio. Vegas outputs the .mpg and .m2v files as well as the AC3 files. However, does anyone have an idea how to mux the AC3 stream into the .TS (extention changed from .mpg) without any synch problems?
