Hello Dave,
how do I know the result of the mplexed mpg file will never takes over the 10.08Mbit/s limit for DVDs? I know tried to burn the DVD with AC3 tone and this time the peak bit-rame and the audio rat are under 10.08 Mbit. At the beginning sound and video is ok, but after 1/2 hour the video is jumping for <1 second. I don't know if it discards frames or something else.
