PS4 DVD/Blu-ray Playback Question

Okay...so I've been having this problem for a while but have finally grown curious about it due to recent developments. For the longest time, whenever I'd insert a Blu-ray or DVD disc into my PS4, the system would "crash" and go to a black screen. I could hear my PS4 trying (and failing) to read the DVD/Blu-ray. HOWEVER, it seems to read some Blu-rays just fine. For instance...every time I insert newer releases like The Force Awakens or Rogue One into the PS4, the playback works perfectly. Every time I put in an older disc like A Bridge Too Far or Apollo 13, the PS4 "crashes" once again. It reads and plays my games perfectly. My mind is blown. What do ya'll think could be the issue?
