Now that GV 800 works, the challenge is to stabilize the GV 900. I can make it work with GV 800 driver, but adjusting channels is a nightmare. This toys have a GPIO that "jumps" between channels and looks like the GV800 settings dont match (by the way, GV 800 shows 4 video devices, and GV 900 shows 8 ).
If anyone has time and skills, are welcome to try to do this board works. LinuxTV.org has the last release of V4L2 and lot of info about bttv driver.

The board shows 64 channels (video0 thru video7 and 8 channels each one), but, looks like, with this driver with the original settings, the channels are "splitted". Looks like, to duplicate the frame rate, 2 chips are looking the same channel.
Playing around with the way ZM grabs the frames, i manage to view 8 channels. Looks like, to grab the other ones, BTTV driver need to be patched. Gonna try to do this.
Feel free to comment here, any help will be appreciated.
