I'm sorry...Should have been more specific!

I am learning (how to post all the necessary info)
No, Pio2001. I cannot read the files at all! I cannot identify any info on the cover too ( any protection or limitation...)
The message I get is "Please Insert disk into Drive I:"
What other info will you be needing?
I'm running Windows XP, the DVD drive is a Compaq DVD-115 (Rebadged Pioneer DVD-115-ME).
Thanks for all the help.
