<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">The system drive on my myth box crashed late week end (chip
burnt out on driver interface board!). I have just rebuilt my system.
Unfortunately my database was on the system drive so now I have a whole load of
.mpg files with myth generated names that I would like to view to see what they
contain.</span></font></p>

whilst I can see the video, on a lot of them I get no sound.</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">I have both an analog (pvr350) and a digital capture card in
my system (nova-T). So I am wondering if this has something to do with it.</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">All the files have .mpg extensions none of them are .nuv.</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">It would appear that some files have audio that mplayer
cannot handle.</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">1. Has anyone got any ideas what is causing this?</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">2. Can anyone recommend a command line tool for displaying
information about the files (for Debian/Linux)?</span></font></p>
<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">3. Can I fix this by transcoding the files, and if so how?</span></font></p>

I think mplayer is just having a hard time getting the audio stream. You can try the file in xine most of the time it will play the audio.
