Mencoder stops very early when trying to convert a .mov file into an .avi file

[Passant]

Hi,

I tried to register on the mencoder-users mailing-list but to no avail. So, I think this is probably the best place to talk about my issue:

I downloaded this screencast:
http://railscasts.com/episodes/199-mobile-devices
(55megs, Quicktime RLE)

I tried to encode it with Video4Fuze to watch it on my Sansa Fuze (Video4Fuze is just a handy GUI on top of mencoder and avidemux)

This failed and gave me a pretty small file, lasting only a few seconds, when the screencast lasts 5 minutes.
In addition, while the audio is ok, the video is way way too fast.

When I try to launch mencoder using the same parameters used by video4fuze, I get this from mencoder:

Lots of "Skipping frame" messages, and then, at the end:

Too many audio packets in the buffer: (4096 in 1121863 bytes).
Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.

I tried with the -ni option, just in case, but with no success.

Is this a problem in the source file? Some flags that I should enable in mencoder?
