My Samsung 1500 player will play dvds fine but on blu rays it will play for a while then just stop or otherwise say the disc is not playable even though the disc has been played before with no issue and I have updated it completely as well. I note that the earlier version of the player I have to date has never had any problem at all it seems the newer models have more issues.

If you have region free blu ray disks then they will play in any blu ray player, the player does not have to be unlocked!

A lot of DVD players are region specific ie. you cannot play US dvds in the UK or from Asia , depending on where the region code for the dvd player is set depends on which dvds are playable

Bluray uses a different laser than dvd/cd playback. You will need to have the deck replaced. Hope it's still under warranty.

Blu-ray require a higher speed when playing a disc so they can produce the hd picture, making the demands on the motor much greater.

All DVDs might not play with a blu-ray player.

Connect the ethernet cable to the backside of the samsung bluray 1500 player ethernet connection with the bluray player power on with no disk & it will automatically update your bluray. It should be work fine after update your bluray. Good Luck!

That usually happens when the laser deteriorates. You can get it replaced but it's not cheap

Buy a cheap DVD player under $50 they play anthing.I have a $600 Toshiba Tivo DVR that won't play some DVD s.My $32 RCA plays anything.Good Luck.

The firmware updates for the Blu-Ray players are available directly from the manufacturers' websites - I won't be able to give you an exact website, because we don't know your manufacturer or model #. Not all firmware updates will resolve all issues with Blu-Ray playback. For instance, even the most recent updates for the Philips and Sony Blu-Ray players do not allow you to watch every single Blu-Ray - but this could change at any point in the future. Unfortunately, Blu-Ray is an evolving technology, and each studio is using a slightly different version of the Blu-Ray format - this has caused numerous conflicts and playability issues. For my money, the Playstation 3 is the best Blu-Ray player on the market - it is future-proof.
