OK, I got the specs on the DVD drive. It is a Toshiba SDR2102. According to 
the manufacturer's specs it is:


DVD-ROM (DVD-5, DVD-9, DVD-10, DVD-18), DVD-R (read), CPRM 
non-correspondence





The DVD I made is DVD-5, disc type is DVD+R. Should I assume from the above 
that the Toshiba player can read DVD-R only? (its not clear to me why the 
specs say DVD-ROM and then DVD-R)



The CPRM non-correspondance thing: this is a code written into to the disc 
itself that cannot be copied. But I assume the de-encrypting software 
(DVDdecrypt) removes the corresponding key, so that the disc ends up looking 
like it is not copy-protected.
