I want to cut a bit out of an .avi file and save it back out to disk, but I get no sound when I do that, and error messages.
I get errors and no sound in VLC, which says "VLC does not support the audio or video format "undef", unfortunately there is no way for you to fix this."
Well that sounds rather hopeless....
So I'm trying to figure out what went wrong. I assumed I didn't define the audio format, but I don't really know how to do that, which of them to pick. The choices in MPEGStreamclip do not include MP3, and that's what the stream info says it is. What to do? Is there a way to get MP3 as a choice? Import it into MPEGStreamclip somehow?
Scratching head here....
I'm on a Mac Mini running Mountain Lion
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

Are you using the save to or export to avi in mpegstreamclip?
If you use the Save to it should not be reconverted.
I just tried trim an avi with divx video and mp3 audio and it worked fine. I used the File->Save to and choosed avi. I'm using mpeg streamclip 1.9.3b8 on mac os x 10.8.2 -

Well the stream info says:
Duration: 0:19:47
Data Size: 160.21 MB
Bit Rate: 1.13 Mbps
Video Tracks:
Xvid, 624 × 352, 23.976 fps, 1.07 Mbps
Audio Tracks:
MPEG Layer-3 Audio stereo, 48 kHz, 134 kbps
VLC on my machine doesn't have a tools menu choice, but the media information only shows audio codec info.

DivX with codecpack does the job
You should download the latest DivX including codecs from http://dist.divx.com/divx/codecpack/DivXInstaller.dmg
After a restart of MPEG StreamClip, the "export audio" dialogue shows mp3 again.
I found this solution on http://forums.macrumors.com/showthread.php?t=1493330, tried it out and it works.
