hello

i'm trying to convert a dvd to h.264 iPod ready with ffmpegX. the dvd has pcm and dts audio, both dvd and ripped (MacTheRipper) files plays fine within apple dvd player and vlc, but ffmpegX doesn't encode audio and the encoded file obviously features no audio as well. when i preview the file within ffmpegX/mplayer, i hear no audio.

i'm on a TiPB 867MHz with X 10.4.6, a cleanly and registered install of ffmpegX v0.0.9.w informs about the vob:
Mpeg 2 Program Stream File [Video/Audio]
Muxrate: 10.08 Mbps
Estimated Duration: 06:12.83s
Aspect ratio 16/9 (large TV)
Interlaced, chroma format: 4:2:0
Size [720 x 576] 25.00 fps 9.80 Mbps
Audio: Mpeg 1 layer 2
256 kbps 44100 Hz
Dual channel, Emphasis: 50/15 microsecs

what do i miss here? after encoding, the log says that no audio was encoded. yes, i already searched the forums, with no appliable result.
