Q about media files & file info (not related to BSPlayer

[Poogie]

Hi,

Hope it's OK to post here a Q about general media file issues...

First some background:

I downloaded a youTube file and converted it to .AVI...
Now, for whatever reason, when I play this file in ANY media player it shows, right on the main screen, some file info like:
Audio Track:
Input description: 44100 Hz, stereo 96 kbps mp2
Output description: 44100 Hz...
Number of channels: 2
Current input bitrate: 96kbps

Qs:
1. What caused this ifo to get displayed in the first place?
2. How do I get rid of it?
3. How do I prevent this from happening again in the future?

TIA for any help on this issue...

P.S.: I'm going to attempt to attach a screen capture... hopefully it'll go thru... OK, where's is the file that I attached to the post???
