So i downloaded some videos, the some i can't "jump" between portion of videos. (49ekdv00405, 49madm00007)
The majority of the videos downloaded though, i can't render with any player or codec, even converter app can't read it. (57bdsr00187, 125umd0772, h_910vrtm00059)
Possibly an issue on r18 side, as their streaming player is also extremely slow, but I think i need a confirmation.
