Error message in Yamb - latest Beta

[davexnet]

Hello, I used YAMB to demux the mp4 video and aac audio.
Then tried to remux them back into a new mp4, but I'm getting the following error:

It gets an error on the aac file, and then says something about URL.
Anybody know what this is about? I used MKVmerge and made a perfectly good MKV file from the same 2 source files.

try to remove the # from your path...

Hi Kurtnoise -
thanks for responding. That was indeed the problem. Your program finished
normally once I put the file in the c:\ root.

This file is actually not what I expected. Seems to be an xvid muxed with aac.
Why would somebody do that?

If I use YAMB to extract the video to avi, it plays fine.

If I put the two streams into an MKV, still pays fine.

However, neither the original mp4, nor the new re-MUXed one will
play, either in WMP 10, or MPC HT. Perhaps the xvid video is confusing it.
I have other AVC type mp4's on my system that play without problems.
I've FFDshow/Haali splitter installed.
