Im writing this just to see if anyone else is having the same issue... I brought my brand new ps4 home at 1 am so excited... and upgrade to the bf4 digital copy and when it asked for the disk I placed it there and it wouldnt go in so I lightly pushed the disc hoping it ffeebut it feels like theres a wall or something obstructing the entry of my blu ray drive... and ive had no luck contacting sony as of yet to fix this matter..
I have a similar problem. Brought my console home and was playing Ghosts and everything was fine. This morning, updated to 1.50 and ejected Ghosts to put in Madden and now it won't accept any discs. It just sits there constantly trying to eject something that's not in there.
I was having this same problem with Killzone. I was playing it and about 15-20mins later it would eject itself and keep trying to eject nothing that was in it, but it seems if you stand it vertically helps for some reason dunno how long of a fix though
