Cannot play new BD or old BD that previously played - Page 2 - Blu-ray Forum

As I research problems with my Panasonic DMP BD80, I'm starting to hear more stories (In several different threads/posts) about new BDs that won't play & existing BDs in a collection that no longer play despite being clean & scratch free.

“Cannot Read Disc” Error messages.

The reason may not be the same in every instance.

I’m hoping this thread will be active & a resource for various types of “cannot play this disc” issues.

Please post which BD, which player & what troubleshooting steps you took & what was the result. Tried in another player & played or also didn't play, exchanged the disc & the new one played or also didn't play. Cleaned the laser manually or with a cleaning disc & did that fix issue. Had player repaired or gave up & bought new player (I suspect this last one will be the most common)

Older players no longer getting FW updates from the manufacturer probably will lead to new copy protection stopping playing of new releases. Forcing one to buy a new player.

Dusty/dirty laser lens causing problems with select discs--not sure why not all discs.

Failing BD player for example, laser going bad & causing problems with select discs--not sure why not all discs.

The disc itself going bad! Not sure this can happen w/o the appearance of the disc being very different but unsure. Disc Rot?

I wonder if most failure to load/play typically happens with movies loaded with BD Live content that slow the loading/reading when 1st load the disc. I know some BDs like Starship Troopers require an SD card in some players or it will not play. Sometimes that SD card is full or needs reformatting or the disc won't play.
This has happened with my Panasonic DMP BD80.

I do think that some players handle scratches better than other players. While troubleshooting my unreadable Point Blank BD, I took it back to BBY & it played in their Sony BDP S185 player. So, I had them try a scratched BD (Warrior) that I had previously replaced. On my BD80 after 1 hour (repeatable) it completely froze with macro-blocking & was unwatchable. However, on the BBY Sony, it merely ‘hiccuped’ @ that spot & went on playing, so a small annoyance vs cannot continue to watch the movie! This experiment proved that a damaged/scratched disc plays differently on different players. Perhaps one has better error control circuitry or better laser.

I suspect these playability issues are fairly common & it is not simply that someone failed to update their FW.
