I recently purchased a LG 55"3D Smart TV and was looking forward to watching some 3D movies. I have a PS3 (120gb version) that I haven't had a bit of trouble with since I've owned it. I went to my local video store and rented Wrath of the Titans and The Avengers. When I started, I made sure to upgrade the firmware on my PS3 to the latest version. I started with The Avengers. I fed the disc in and about 20 seconds later the PS3 makes a noise like it is ejecting the disc. But it doesn't and the disc never shows up in the Video list. I did the same thing with the Wrath disc with the same results, but after trying it several times, it finally showed up in the list and played normally. Unfortunately, I never did get The Avengers disc to show up or play. Is there some sort of protection on the disc to prevent it from playing on the PS3? Is there something I'm missing that I need to do to get 3D discs to play? Thanks in advance for any help.
