OGM audio track switching problem

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open an OGM file with more than one audio track
2. Play the file
3. Select an audio track other than the default

What is the expected output? What do you see instead?

The audio track is not changed.

What version of the product are you using? On what operating system?

Tested with 0.7.0 Ubuntu package and svn r1158.
MPlayer is 1.0rc2-4.3.2

Please provide any additional information below.

I'm not sure if this is a bug in gnome-mplayer or in mplayer. In gmplayer,
when I open the same OGM file and switch the audio track, it gets changed
indeed, but the playback of the movie restarts.

Can you please point me to a file with more than one audio track that exhibits 
this
problem? I have tested with DVDs that contain multiple audio tracks and they 
work fine.

Here's a torrent file, containing OGM files which cause me the described 
problem:

(you have to register in order to download the torrent)

Sorry, I can't download a 19GB file. I'm on a very slow connection and this 
would
take days for me to get. Can you provide something smaller.

You should be able to select a single file to download from your torrent 
client. The
smallest .ogm file in this torrent seems to be around 135MB.

Sorry, but until now I haven't encountered other .ogm files that cause this 
problem
(probably haven't encountered dual-audio .ogm files at all), so this is the 
single
example to which I can point you. :)

Sorry, forgot to mention - the file with size of 135MB is '[AHQ] Rurouni 
Kenshin - 81
- Conspiracy Of The Beni-aoi.ogm'.

Ok, I got part of that file... it might be a bug in mplayer itself as I can get 
it
work with mplayer by specifying -aid 1 on the command line, but I can't get it 
switch
while playing. Might want to open a bug upstream.

Sure, I will.

Just found this one -

Seem like setting the demuxer to lavf for OGM files really helps (see the 
attached
patch).
