Using DVD2SVCD with Robshot method for DVD creation

You can't. At least not the original method. By defininition the Robshot method takes manual intervention. Have a look in the advanced forum there is a very long post on this. Mark

the main advantage of the robshot method is maintaining constant quality with every rip that you do.

I use my PC all the time while I am encoding. Just set the priority to low in DVD2SVCD and other tasks will have CPU priority. This doesn't really increase encode times much since most programs use very little CPU. Just don't expect to be able to do some major gaming while encoding. Mark
