I found a solution to start Dopus4 via Early Startup Control from HD, DVD, ISO.
Now you will no longer have to run a script but run the Dopu4 binary directly.
Basically once you get to the Grub, via Grub/BootMenu you will be able to access on "Early Startup Control", then choose the "Boot With No Startup-sequence" tab, and from the command prompt just type Dopus4 and send, I see Video and Screenshot !
