Hi I have an iMac running Lion and it suddenly started working in the background and not responding whilst I was watching a DVD. I had to shut it down and now I can't login to a user it just shutsdown if I log in as the user that was using it with the DVD. If I login as another account it just goes to a grey scren with endless looping circle and I cant even eject DVD.

How are you trying to eject the DVD? Restart holding down the mouse button until it (hopefully) ejects? Or restart and hold the eject key until it spits out.
To eject the DVD at startup hold down one of the mouse buttons. If you are using a bluetooth mouse you might have to connect a USB mouse to complete this action.
As to why the system isn't fully starting I suspect you have a hard drive problem. See if you can boot to the recovery HD partition by holding down the Command + r keys at startup. Run Disk Utility to verify the drive.
thanks but tried all the suggested ways including single user login
Then it could be your Superdrive failed and that is why the system hung and you now can't eject the disc.
If all the normal methods aren't working, and you are out of warranty, and at your own risk, you could try this:
Cant start iMac or eject DVD
