Hello Fabio, I have had the same problem when coding mpeg-files from video streams of my digital camera. I have sent a patch for my problems to the mplayer-dev mailing list. Fabio have a look to the bug report "noisy audio resample, no duplicate frames for MPEG, no audio stream for MPEG" Best regards Dirk - E-mail: dirk-holger.lenz@tek.com
