Re: Can Netjuke create MP3s on the fly?

Hello,
    After doing some more testing, I have discovered that this does not  
work if there is a quote "'" character in the path of the file or in  
the id3 tags of the mp3.  I haven't had any luck in figuring out how to  
escape the strings.

    If you have any ideas, I would appreciate it.


Thank you,

Paul
