Decrypting audio based on elapsed time?

[Chris_147]

Maybe first a word of explanation.
A friend of mine is married and we have a tradition of making it a bit 'difficult' to receive the wedding present (money) from the friends. Sometimes it is in concrete, sometimes we put sand in their house and hide the money (coins) in there, ...
This time one of the tasks is to recognize audio fragments of the Star Wars movies (he's a big fan) and tell on which time they are audible in the movie.

So I was thinking of getting some 20 recognisable fragments (1-5 seconds) from the movies. But is there some program that would allow me to rip the audio based on the timeframe? Or do I need to rip the complete soundtrack and copy the correct fragments myself?

Not the most obvious decrypting question I'm afraid. But if it possible it's a big timesaver...

I'm not quite sure what your question is, but this is how I would do it:

1) Decrypt files onto HD using DVDDecrypter.
2) Use DGIndex to demux the ac3 audio tracks.
3) Use BeLight/BeSweet to encode the fragments.

BeLight/BeSweet supports partial encodings, so the hardest and most time consuming part would be actually figuring out the timestamps.

I was using BeLight 0.21 with BeSweet 1.5b31 but had a problem with partial encoding: after start time of about 550 seconds, the output file became more and more noisy. I'll just do it with and audio editor.

Make sure you downmix properly, or you're going to have some very quiet Vader breathing and Han quips. I suggest grabbing the 2ch track from your DVD(s), demuxing it to wav (make some HDD room), and then edit it, as audio editors love .wav for editing.
