Trying to play Video DVD on Ywo different Netbooks with Two different 
external USB DVD drives.

Two different Video DVD's and I get the Same Error message;

Playback failure:
DVDRead could not open the disc "/dev/dvd".
Your input can't be opened:
VLC is unable to open the MRL 'dvd:///dev/dvd'. Check the log for details.

Tried the Mplayer and Xine and have the same problems.

Both Netbooks have played the same DVD's about a week ago ,but not now.

Both video DVD's  will play without any Errors on standard Laptop with a 
CD/DVD drive internally, With Fedora 14.
