DViCO FusionHDTV DVB-T Dual Express2

DVico Fusion HDTV Dual Express2 PCB showing component labels (give or take poor photography)

A new revision of a hybrid DVB-T PCIe card from DViCO.

The previous revision (Dual Express) has DVB support in mercurial, but not in the mainline kernel. This revision is not currently identified correctly in linux.

Overview/Features

Able to deliver one analogue channel and one digital channel simultaneously or 2 digital channels. High definition resolution is 1920 x 1080. Features a power switch pass-through to allow it to turn the host system on automatically.

Making it Work

According to http://www.linuxtv.org/wiki/index.php/DiBcom_DiB7xxx the DB7070 has a DIB0070 RF tuner with DIB7000 demodulator. I was able to get the CX23885 to load 2 front ends (that dont work) and the DIB7000 using a hybrid of Hauppauge WinTV-HVR1400 & DViCO FusionHDTV DVB-T Dual Express settings. I dont know who to work the DIB0070 (I guess I need to replace the xc2028 references)......

Remote Control Support

Have not attempted using remote with this card. Remote works ok with the USB receiver from a DVICO DVB-T Plus (slightly different repeat timing).
