Is this a new form of copy protection? Any suggestions?

[hipsterjedi]

I have been backing up my DVDs to VCD for about a year. I have settled into using TMPEGenc for the final encode and mux into VCD format. I have encountered a new problem on two of my DVDs, RED PLANET and 3000 MILES TO GRACELAND. The audio on both of these movies are always ahead of the video after the encode to VCD. Upon close inspection, this is what I found to be the problem:

On each movie there is an extra segment of video information added in (usually a production company intro or the FBI warning)that is not contained in the audio stream. When muxed together the video obviously gets behind due to this added material, the audio goes on playing on track. I tested this by watching the movie on my DVD player, then observing the video information that I got from DVD2AVI. On the DVD player the extra video is NOT present. Only on the ripped video stream can the extra video be seen.

The big question is has anyone else incountered this? And if so, do you know of a way around this? Needless to say this may be a clever new technique to prevent copying. Unfornately, I cannot back up these movies to watch on my computer at work that does have a DVD-ROM.

Any information or advice about this would be much appreciated.

Thanks

That's known as audio shift. You can correct it using a tool like Virtualdub and setting a delay on the audio. Then frameserve it for encoding.

You could also time the extra video on the rip and then set TMPGEnc's source range to cut out the extra video and just encode the movie and audio together where they are supposed to start.

HERES WHAT YOU DO!!!

Ok..in DVD2AVI, Extract Just The Audio first. THEN Go Back and if you have the statistics window open..drag the bar to where the movie starts (would be frame 0)..And Just do the Video..Then Just use TMPGEnc Like you normally would..I found that same problem w/ "Miss Congeniality"..and my solution worked Adios Amigo!

This isn't anything new. Just a different way of layout on the movie. It just has a video track start way before the audio track. But DVD2AVI will rip to a new audio track anyway as if there was one there, and it makes a delay.

Don't know if this was totally covered, I kinda jumped in without reading fully :O !!!

Deja Vue! Promises to yield superior quality VCDs! No one can tell the difference, they are tottally foold! "Is that the DVD???" is the common question, even to the trained eyes.

Its the process I use, and will use NOTHING else, quality is my utmost priority!
