    Checking md5sum is always a good idea, but it isn't a life-or-death issue- if it installs and runs fine, it probably is ok. Unless you're worried that someone might have compromised the ISO and presented a security risk, it should be fine.
    When you boot from the DVD the first screen you get will ask if you want to install or "try" Ubuntu- try = run from DVD.
    Good luck!

    This documentation also applies to Live-DVD's:

    Nobody has updated the terminology yet, is all.

    As I understand it, the graphical DVD-burning utility (Brasero, xfburn or K3B, for example) perform an action similar to using an md5 to verify that the image burnt to the disc is the same one indicated on the header of the ISO itself. This also goes for veryfing the image after it is downloaded. It is simply a listing of what is on the image itself.

    If you are using the command line to burn your image (i.e. using dd), you are encouraged to use the md5's for manually verifying the DVD both before and after the burn. Kind of an "either/or" situation. Many of ubuntu's graphical applications are just automated and attractive ways of doing the same operation that takes place in a terminal. My opinion: no need if you verify the disk through K3B, Brasero or xfburn.
