Same issue: DVD spools up to ungodly speed and makes alarming rattling noises,
followed by VLC refusing to play the disc. So does Ubuntu Movie Player.
Ubuntu Version: Lucid Lynx 10.04
Hardware: Dell Latitude E6400 ATG laptop
DVD drive: Ubuntu cannot identify type - returns 'unknown type' under disc
properties.
I can confirm this is not a region issue. My laptop is dual-booting and under
Windows 7 this DVD player plays Region 4 (my home country's region) discs
without any problems. Except one: VLC for Windows makes the same ungodly
speed/rattling noise/refusal to play, very unusual behaviour for VLC under
Windows. I must play DVDs through Windows Media Player instead. So I don't
discount this could be a hardware issue. In my case I get the strong feeling
that the system's failure to identify disc drive type is behind these errors.
