I just burned my 1st BD-R I thought for a while I had 2 coasters. Yesterday I burned a remuxed copy of Flyboys. The file was 23.7g , very big. It burned and plays but had an “invalid block address” error on both test BD-RE burns. Both worked so I thought I would burn to bdr, started the burn and within a few seconds is spit it back out with some kind of error. I remuxed the film as before and tried it again. Now some of the space was used and nero said the disc was not big enough. So I stuck in a 2nd one and it spit it out with the same error. For some reason the size of the BD-RE copy was smaller than 23.7 so I copied it using the same failed disc and it worked, except for a little garbled playback about 15 min in. Not more than a couple of minutes. So far it’s had no other errors. So after this error I’m thinking 1 or 2 safer way to burn a write once disc. First always use a rewritable 1st. After successfully burning the rewritable do the burn again on a write once. Or copy the rewritable and use a BD-R. Are garbled parts of the film something that happens?
