Can someone help us with 500hd v2?

Have a linux oscam server running. #6432 (know its old but working)
Now my friend have bought a new DB 500HD v2.
I can see him connected to server but he dont have a picture.
He have also a Vu+ solo that works with picture.
But we cant get DB to view picture.

USERxxx OFF ON xxx.xxx.xxx.xxx port newcamd (mgcamd) 12.09.13 19:05:21 00:09:36 0B00:0135 Canal+: Emotion by canal (cache) (105ms) 00:00:04 OK

He have taken the mg_cfg from vu+ to DB
Should I change something in that configuration

We (read I) managed to fix it. Change under B: in mg_cfg. Now it works.
My friend told me that he HAVE changed it already but did forgot to save the file.
