problem with OpenPictureDialog / CD serial Number

[LastCyborg]

If I put an OpenPicureDialog (using the default configuration) on my form and I click twice on it,I see the preview working very well.
But when I run my App some filters dissappear.
And if I remove the filters and I just put for jpg's it fails why??

Do you know how can I retrieve the CD serial number?
Let me explain more about it. Every disc (CD or DVD) has a serial number which makes a disc unique. That's the number that I need.
