Thanks for the quick reply lightning!
If i play the bluray (m2ts file) from the folders, before i build the ISO, they play fine on the media player. the problem occurs at the ISO building stage & always in the same spot. I have tried building the ISO 3 times now, & it happens in the same spot.
I used BD Rebuilder & the ISO created from BD Rebuilder works fine. I have close to 300 ISO's on the HD that the media player uses & this is the first time I have had an issue. I also have tried streaming the file & iso from a pc, with the same results--so i would rule out multimedia players HD.
Dont really know why? My thoughts were to try slowing the speed down----newhaven
