They never locate the sample in the main movie file. Same behavior with srs.exe preview version. The things that make them special is that they use CRF and DTS-HD, but those things worked before.

What is left are the S_HDMV/PGS subtitle tracks.

    I don't have that release, so I made a sample of a similar file myself, and srs would create and verify the sample just fine.

    The source file has two DTS-HD streams, one PGS-stream and one VobSub-stream.

    Maybe the samples have some sort of defect from the program they used?

  3. Gfy reporter

    That could be possible. Which tool did you use to create the sample? If it's the tool, I guess they use a custom tool though.

    Xvid .avi LOL samples aren't possible to reconstruct either. (they do, but look weird and don't match CRC32)

  4. Gfy reporter

    The amount of track data for the two subtitle streams seems to be a lot for just the sample compared to the subtitle streams in the full movie file.
