Only two Outputs instead of five?

Hi,

I want to play PT 6.5.3 (pro) with 5.0 surround.

Soundcard Motu 828 (external) and internal EMU-1212m.
Win7 64, HP-Z600 2xXeon, 24GB Ram

In the Page Output - soundrecording - mic-mode
i see and manipulate the 5mics, can see the 5 Outputs but only two of them are active (green light)
Output 3,4,5 are without grenn light, right mouseclick without Effekt.

Options - devices - ASIO - MOTU-asio - i activatet analog 1 2 3 4 5
Testtones solo are o.k. and i can hear them on the correct Loudspeakers L R C SL SR

On the second music PC  i the Studioroom PT-5-pro ist installed with RME HDSP and it works fine in surround mode with all 5 Channels.

Is this a bug in Vers.6?
Something wrong in my configuration?

History of the installation: first Motu-828, playing Vers. 5 in Stereo and surround, then firewirecontroller was defect, i changed to the pci-EMU card used the two anlog Outputs. Updated to Vers.6.
After the new firewire controller arrived i changed back to the Motu.

Anyone any ideas?
(and sorry for my bad english)
