problem rendering files with custom resolutions

Last night, I exported an MPG stream and put it into iTunes. The MPG in iTunes plays just fine. When I converted it using iTunes, though, the resulting file had no sound. What is going on here? If I use the Cinelerra standard YUV4MPEG pipe, with -target DVD, the video renders fine and comes back into Cinelerra in its' entirety. But when I use a custom resolution size (480x320), the video track gets truncated shorter than the audio track when I reimport the rendered MPEG back into Cinelerra. So something is definetly wrong about how Cinelerra is rendering files with custom resolutions. I guess I'm going to have to enter a bug because no one seems to be responding to my posts on cvs.cinelerra.org.

Tonight, I'm rendering the file as MOV and hopefully that will solve my issues. Of course, this is all extra work, because my original intent is to do all of this within Cinelerra, instead of having to go out.

More evidence of strangeness is that even though xine and mplayer played the MPG, ffplay played the video stream, but there was no audio. That may be telling me something.
