Has you ever had this happen?
I have a rented DVD that played fine on my Denon 1600, it played fine on a $30.00 no name player in my kids room, but it would not play on my LG. The LG is the only one of the group that has HDMI or upsampling, I wonder if that might have been the reason. I can't remember the LG's model but it's supposed to play just about everything under the sun. So I ruled out a Region code problem. The Denon is the older of the group. It wouldn't play a bootleg disc a friend brought over but that $30.00 player would. I thought that may have been because those cheap players use computer DVD drives, or it could have been the Denon's age.
Any ideas or similar experience?
