Hi, I have an MPEG elementary video stream and audio stream in separate files, that I would like to transcode to DVD format. The video is already in a suitable resolution and refresh rate etc. for DVD, although its aspect ratio flag is incorrectly set as 4:3 instead of 16:9. I want to transcode the audio to AC3 and add it to the video stream, which should be passed through.
My reading of the manpage suggests that the raw export module and -P 1 flag should accomplish this, however when I try this, I get strange errors about AVI files: $ transcode -i program.mpv -p program.mpa --export_prof dvd-pal -P 1 -y raw,ac3 -N 0x2000 -E 48000 -b 192 --import_asr 3 --export_asr 3 -o program.mpg -q 3 transcode v1.0.2 (C) 2001-2003 Thomas Oestreich, 2003-2004 T.

Why is export_raw trying to open an AVI file? I am using the packages from http://www.debian-multimedia.org on a debian testing x86 Linux box. Thanks, Andrew
