Why Is This Dahua DVR Image Quality So Bad?

I obtained the latest version of the new "S2" version of HCVR5216A-S2 for testing. These models have no controls on the front panel and look more slick. We were looking at using these as a great way to incrementally upgrade the many SD analog systems we have to HD (HDCVI and IP). This unit auto detects SD or CVI on each channel and also accepts IP. It also supposedly allows longer UTP (CVI) runs with baluns than earlier models.

We tested the unit with 8 SD analog cameras running with all set to the highest quality settings (D1, 960h, VBR and "6" - highest quality, max bit rate). However we found the quality of the live view and esapecially playback to be very poor. We even hooked up an old Kodicom system with duplicate feeds at CIF and it was significantly better! One other unit we tested just for kicks ($120 960h 8 Channel Aliexpress no-name brand) had a great picture (and does 30fps each channel).

Anyone have any insight or comments into why this would be? Anyone tested the earlier versions (HCVR5216A-V2) Tribrid with analog? This is our first test of Dahua equipment. We used the exact same monitor in these pics. Quite disappointing unless something else is wrong but have tried all settings. Unfortunately it seems to show what the unit is actually capable of
