Qsee DVR working but only getting low res sub-stream

[John Sutherland]

Any suggestions on how to get the main stream from a QSee QT428 DVR? Looks like I am getting the sub-stream.

The Cameras I have are:
Q-See QSM5265C
1/3" Enhanced Infrared Cut Filter, Color
520 TV Lines MAX Resolution.

Qsee shows that the main stream is 704x480.

Blue Iris config:

Thanks,

John
