I'm sort of working on decoding the JVC series of DVD recorder hard drives.
Across several SR and DR models I have noticed the MPEG video appears to be in the same MPEG2 format, but stored in what looked like a different MPEG2 Profile format.
I'm not an MPEG expert.
The end result is when they play on Windows Media Player or VLC, strips of video within a frame are rendered crisp and clear, but then interlaced with strips of gray or gray inverted video.
I have seen this so much across so any models I'm confident its either an alternative or custom profile, it always looks the same.
Its a fringe subject so I won't get frustrated if no one has a clue.
I was just hoping to figure it out so we could add some JVC DVD and Blueray recorders to the
Isobuster list of supported dvd recorders for video extraction.
Happy holidays.
