Were you able to try the DVD in another Computer, or at least on another DVD
drive?

Sounds like a hardware failure from the way you describe it. If you have
System Restore running you could try rolling back your system til before all
these problems started occuring. If it's a software problem then something
you installed on your computer could be causing your dvd drive to fail
reading.

Might call HP, since it's a new computer you're probably covered under a
hardware warranty. If you bought your system from a local brick and mortar
store you might take the system back and have them test it for you. Keep in
mind if it's a software issue you might have to pay for a fix unless the
system is really new, then see if you can get an exchange (computer
warraties don't cover software problems, only hardware).

Hope that helps...
