I'm trying to reencode an xvid of a tv episode to make it smaller. The original plays fine.

The info says audio: ac3, 48000, stereo 192kbps.

Under audio track, it comes up with ac35.1 in en, du and es; and ac3 (stereo).

I have tried various options, selecting the passthrough and mp3 options, using different audio tracks.

It always has an error in the coding, though, eg.

"AVI file format detected.
AVI: invalid audio stream ID: 128 - ignoring (nosound)
AVI_NI: No audio stream found -> no sound."

Would appreciate any tips.

Regards,
Bruce
