Printing MP3 Encoding Information with mpgtx

MP3 music files are MPEG 1 layer 3 files. Let's see if mpgtx can print MPEG encoding information from a MP3 file:

C:\temp>\local\bin\mpgtx -i xxx.mp3
Skipped -2 zeroes at start of file
mpgtx: AT EOF - please stop me!
mmm, this file does not start with a pack, offset: -2
use the desperate_mode switch as the first option -X to search for 
a header in the whole file! if you want to force the operation. 
May yield to an endless loop if no valid header is found!
Does not even begin with a 00 00 01 xx sequence!
