No, this guy is dogshit. You can't blindly make hybrid files by combining DV and HDR streams. Many of them have different grading and cannot just be slapped together willy nilly. The people making these "hybrid" files NEVER fucking check to make sure there isn't a brightness mismatch. I wish they'd just release the P5 files instead of this P8 hybrid fucking bullshit. DVSUX NEVER made these hybrid dogshit files.
Also, rarbg required people to clearly label any "hybrid" files. Apparently t.galaxy doesn't give a flying fuck about properly labeling things...
