I've not had anyone else report this particular problem yet, although there's only 10 of this particular model of laptop in use and a majority of them are with admin staff so there's every chance the same problem exists on them all, just no one else has tried playing a DVD movie yet!
I'm going to look into it further tomorrow, I just ran out of time today.

OK, this issue is much more widespread than I thought - it's affecting a lot of our staff laptops, but seemingly not all.
This occured on a Dell D530 earlier.
Call - Can't play DVD on Laptop.
Attend call, and find it's the same issue, so I spent about half an hour fiddling around and trying some of the suggestions, and it made no difference, but I did notice the following.
If the laptop is booted with the DVD in the drive, then it starts up fine, and recognises the DVD as normal, as per the screen dump below.
Then I ejected it, nothing wrong here recognises it as a DVD / CDRW drive which is correct for this laptop.
Put the disc back in and this happens
and take it out again and this happens
This squence of events happens in the same way on any machine that's suffering from it.
I've un-installed CDburnerXP which we had on all the laptops to see if it made any difference, and just in case also un-installed the Klite codec pack which we also had installed
I'm running out of options - next I'm going to have to re-build my staff build from scratch to see if I can work out where it's gone wrong.
Anyone got any further suggestions?
On one of the laptops if you use a windows xp disc and install windows xp with drivers for motherboard / chipset etc does the dvd drive work ok now or is it still the same ?

I'm going to build one from scratch during Halfterm and then do our build process one program at a time and see if I can work out at what point it goes wrong.
Cheers for your help
In the system tray you have the network icons, Fog service, Volume, Truecrypt, Lanschool Teachers console, Updates and eject hardware icon and Promethean whiteboard tray icon. All our laptops are identical in this.

I had almost exactly the same issue last week while I was testing the VLC Media Player package I am currently working on. In my particular case it was because the registry value shown below was set incorrectly.Anyone got any further suggestions?
To play DVDs in Windows Media Player by default you should set the default value in the 'HKCR\DVD\Shell' key to...
If you would like VLC Media Player to be the default, you need to use this value instead...Code:Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\DVD\Shell] @="Play"
Obviously VLC needs to be installed first for the second example to work.Code:Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\DVD\Shell] @="PlayWithVLC"
Failing that though, Microsoft's AutoPlay Repair Wizard might be worth a try. Run this, install your media player(s) of choice and then play a DVD.

Solved this in the end, purely by chance.
Basically I ran a restore on the security settings of the affected machine by using the command
Which put right whatever was wrong. I was origenally trying to solve another problem, but it's also solved this one as well - bonus!Code:secedit /configure /cfg %windir%\repair\secsetup.inf /db secsetup.sdb /verbose
Still have no idea what caused the problem in the first place, but at lease I can fix it now!
