Question: Why can I not set my recorder to record D1 on all 16 channels?
Answer:
Please see the maximum record rate of the unit below:
             D1 = 100fps (6 fps per channel)
             HD1 = 200fps (12fps per channel)
             CIF = 400fps (25 fps per channel)
To set the DVR to D1, you must first reduce the frames per second down to 6 fps. Copy to all channels and save.
Then change the resolution to D1, copy to all and save again.
