USB DVD drive not mounted any more

[cycobyco]

XBian version: XBian 1.0 Beta 1.1
Overclock settings: Xbian (840mhz)
RPi model (512mb)
MPEG2 key

Problem description:

Since I updated to XBian 1.0 Beta 1.1 my USB DVD drive is not mounted any more, which means there is no "Play Disc" option in the XBMC menu any more when I insert a DVD (with/without css). However, lsusb -v shows that the device is recognized.

Before the update I used Xbian 1 Alpha 3 (or earlier) and I had installed libdvdcss.
I could play DVDs (even with css) and iso files perfectly.
So everything worked well with regard to DVD playback.

So whatever you changed, could you change it back or at least offer an opportunity to download pre-Alpha 4 builds?
