This might be your problem, for USB do you have a 1.1 controller or 2.0 USB controller? lsusb -v|grep bcdUSB You'll want to be using USB 2.0 > Internal DVD 1: Putting a DVD in this drive causes the light to flash as > if it is reading, but no icon comes up and it does not become > accessible.

What kind of cables are you using? If you don't have shielded cables it's worth it, they're cheap. Also try using single-word DMA instead of multi-word DMA and see if that helps. Good page for all this: http://axljab.homelinux.org/Hdparm And further you may want to build your own custom kernel, there may be specific settings for your hardware that aren't enabled in the standard FC4 kernel. bon apetit, Richard > > In Xine, when attempting to play a DVD, or an audio CD from my DVD > drive, I get the following error: > There is no plugin available to handle 'dvd:/'.
