Overburn or Truncate for Blu-Rays

[BlizzardUK]

Just went to burn a home made BD ISO which is 25,025,314,816 in size. My disc says it is 25,138,692,096 so will need to overburn or truncate. Any idea which I should choose to get all the data on the disc ? Or will there definitely be some loss of data ? 

 

Thanks.

There will be some loss. Try and trim / compress what you're burning a little bit.
