Waht was your exact audio encoding command ? Did you use the -R option ? > > What length have all the files ?

Is there any better way? If you let lav2wav do that the length should be ok. The problem is now that lav2wav lookes only at the first file, and if you have silence there it does not look at the other files. And generates for that files silence too. You could now generate the first silence wav's, than the wave with audio and afterwards again silence. And feed the wav than into mp2enc: lav2wav -R title.avi >title.wav .... lav2wav massimo2.avi >massimo2.wav lav2wav trans02.avi >trans02.wav cat title.wav ... massimo2.wav trans02.wav | mp2enc .... That had worked well on my computer. If that does not work well, you can glue the audio together with snd or audacity for example. auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
