Hakon, the problems with dm800 and diseqc are the same like in crappy 500 fakebox?
Is dm800 the same fakebox ?

No the problem are not the same in the DM800.
In the case in my answer it was a crappy fakebox that could not give enough power from the tuner.It did work with a genuin DM600.

The switching problem with DM800 are even with single LNB not just with Twin/Quad.

I have had the same switchingproblem with my 5xSpaun 420 + 1x Spaun 410 (cascade) and 17 LNB (Single and Twin), untill i put on the repeat DiSEqC command.The box is an 7020.

I have tested this setup with my DM800 and with correct setup in box it also works great. I have tested to replace the SAR410 in the cascade with different committed switches and still ok.

Today my DM800 runs perfect with 2x Twin Smart 1x Quad Smart and just one SMART 4/1 SUS44 DiSEqC iso >25dB.
And i know many who use the same LNB and switch with there DM800 and works great.

There can be some reason for your problem. Is the 500S-box a genuin Dreambox ?
If not i have seen this problem recently.

The crappy 500 fakebox was not able to deliver the power that the LNB and switch wanted.
The setup was as follow
500 fakebox ->EMP 8/1-> Octo LNB = not working
500 fakebox ->EMP 8/1-> QuadLNB = working
500 fakebox ->Smart 2/1-> Octo LNB = working

The Power Consumption for the components are as follow
Single 90-110mA
Twin/Quad 190-220mA
Octo 210-240mA

And for the switch
EMP 8/1 50mA
Smart 2/1 30mA

After i told him to try with another genuin satbox he bought a genuin DM 600s and everything worked as it should.
A genuin Dreambox tuner are spec to deliver 500mA max

The conclusion is dont use crappy clones
