I believe that FF/RW is not possible on m2ts files over a certain length on the x700. People ran into that problem with the Lord of the Rings extended cuts. If you search this thread, you'll find some posts about the issue.nekno wrote: Fri May 28, 2021 12:01 am Anyone know what would cause FF/RW to work on the Sony X700 playing an m2ts dvhe.07 FEL file from USB that's 2mins long, but not on a file that's 3hrs long?
The only workaround is to use TSmuxer to create a Blu-Ray folder output using the mpls of the main film and place those folders created by TSmuxer in the root of the USB drive. Then you'll be able to FF/RW. The catch is that you can only have one film in the root at a time.
