I ripped Star Wars Episode IV, V and VI using the newest DVD Decrypter without any issues, burned them to Dual Layer DVD's and they won't play properly on my Denon 1710 DVD player. It just freezes up on the screen where it says "This motion picture has been rated PG blah blah....". I can play them just fine on my Panasonic DVD Player/Burner for my PC though. I don't think it's the DVD blanks because I've burned a few others (Pink Floyd - The Wall, Troy) and they play fine on my Denon.
I'm wondering if DVD Decrypter removed something from the originals (like a protection of sorts) and it's confusing the Denon player.
