Hi Tore,
Glad you've got it working. Well done!
The best way to use a USB stick is for multiboot using FlashWizard 5.0 as the multiboot manager.
As for P*Vu I have not seen a Dreambox emu that opens channels using it, unless someone else knows better?
Ask if you need help with multiboot and I'll point you to a thread (which I can't at the moment remember the title of), where I've recently helped someone else set up multiboot.

Just checked, the thread to look at is called 'Var 97 percent Full' and was posted by 'rhurbarb' my reply 3 days ago describes how to setup multiboot.

DreamBoxEdit is indeed good for transferring sat settings etc (including favourites lists) between images.
When using FW5.0 to install images to multiboot , FW5.0 will automatically copy all the settings from the active image to the new image as it installs it. You can then boot and use the new image straight away with all settings already there, it's great!
Not sure what image you're using but many have internet download of latest emus and k*ys (Hydra Phoenix/Poseidon, Gemini 106/105, DBF Revolutions 3.1, Trillenium v 1 .....). Mary's are a download on the Hydra images.
Hope this helps?
73 & good luck.
