Compressed folder will not extract!

I had GB's of old work files, so I decided to put them all onto DVD to save
HD space. To keep the files safe, I put about a GB at a time into compressed
folders, and added the same password to each compressed folder. From there I
burnt the compressed folders onto DVDs. I have extracted the files from DVD
onto my HD a few times before, and I deleted the extracted files every time I
was finished refering to them. Now (a few months after installing SP2) I
tried again, and Explorer keeps telling me that I'm using the wrong password.
I KNOW that I am using the right password. Is there anything that anyone
knows of that could be the problem OTHER THAN the wrong password? ~Thanks
sooo much!
