thx for the link and all of your suggestions. I now have dvd decrypter and the 1.4 firmware.
I am very much a newb at this, so I was not aware of dvd decrypter.
I burned one of the Verbatim dual layer blanks after ripping demonlover using DVDDecrypter. The layer transition problem is now fixed and my copy will play all the way through on my Denon DVD2200. It's good to know (or assume) that my DVR109 is not the source of my problems so far.
I still have one problem though and that is that anytime I select an item from the top menu (scenes, audio setup, etc) it skips through the subsequent pages and starts the movie without any further input from me. Any way to fix this?
