I don't believe that the DVD has been 'remastered'...I could be wrong.
Yes, the marketing video is pretty crappy...
However, the DVD that I rec'd years ago is, obviously, of older quality but is certainly very usable. Yours couldn't be any worse;-)
More importantly, the info contained coupled with Greg's style is what makes this a great value.
If this really concerns you, contact PM customer service directly by email or Live Chat...
Good luck.
