I know that there a special kind of diodes (germanium instead of silicium) that have a voltage drop of 0.2V instead of 0.6V.
So, in the signal range of 0-5V, this is a signal drop 1/20, so 4% loss.
Anyone tried this before?
I'm sure I'm not the only one who struggled with this 'problem'

Hi Audrey
What you're trying to do is entirely possible. I run 2 x 1 watt greens alongside my 1.5 watt RGB, all from one QM2000.Net.
The result looks great and the greens are fully analogue modulated. Rob (Stanwax) did the wiring for me on the greens that allows them to be fully analogue modulated. He used diodes on the inputs, but that's as much as I know. Perhaps you could drop him a PM, I know he's quite busy building projectors at the minute. If you PM me i'll give you his email address.
Hope you're keeping well, we haven't seen you here for a while.
Cheers
Jem
