PS3 Won't Play Blu-Ray Movies

[thesmf]

this is a bit old now i know

i cant make heads or tails of this issue?

got 2 films it refuses to like and keep buying more films that my ps3 plays fine

1 is the semi documented dodgy spiderman 2 disc thats known to have issues (boots fine in my panny bd and xbox one), not an issue i had a promo copy of the trilogy i planned to sell as it was still new and sealed so ended up opening that and watching it fine from that set (nicer having a single case for all 3 films also)

the 2nd is rampage with dwayne johnson, plays fine in my panny bd player downstairs but hates the ps3, or so it seems, 1st time i decided to watch this and found it wouldnt boot after a few times i decided to call it quits and watch another film, so watched ready player one as that was also purchased at the same time and i hadnt seen it, that film played fine, then watched all the extras after it, once that viewing was done i put rampage back in (ps3 defo warmed up by then) and hey presto, film booted up no problem, so i was like must be a stupid ps3 glitch

no, still doesnt like this disc, but plays basically everything else i throw in it

must be a clear incentive to buy a UHD player (ok i still have a panny bd to use and my xbox one), only thing i havent tried is the turning the player upright to see if gravity does its part with the loading like previously mentioned as my ps3 is sat in the middle of my av shelving unit so its not really viable
