I saved the PST file to my hard disk, and backed it up to DVD using

The PST was already on the source PC's hard drive. Why did you "save" it
again? How did you save it? When you burned it to the DVD, was Outlook
closed?

I subsequently restored it onto my home machine
ensuring the same filename is used.

As long as you did not overwrite any PST of the same name, you should be OK,
but what do you mean by "restored"? Describe the process exactly.

The file has the Read-only option unchecked.

And you put it on the hard drive before trying to open it, correct?

Any thoughts as to why I am unable to open it?

If the message says you don't have permission, then either the file is still
read-only or its ownership/security settings are incorrect for its new
location. If it's a different message, like "not a valid PST", then the
process you used to transfer the PST has damaged it and you will need to
retransfer the file. All you need to do is, while Outlook is closed, copy
the ORIGINAL PST being used by Outlook on your PC at work to the transfer
medium, take that meium home, copy the PST on it to some folder OTHER THAN
the default folder Outlook would use, make sure it's not read-only, then
start Outlook and open it there with FIleOpenOutlook Data File.
