you can start by actually describing your problem.
program versions are nice. ("most recent" is not a version)
what are the exact error messages?
at what point in the process do you get them?
if during burning, what is the media ID of your blank media? burn speed?
region/format/edition of the disc? (ie R1 USA, NTSC, widescreen special edition)
the more info the better. we can't help if you don't tell us anything!
