The bitrate is just above max (2530). In this case, D2SRoBa, really should have swithced to CBR MAX automatically, instead of OPV Q=1. That is a planned feature .. sometime...
You could try selecting 1 CD: if you think the quality is OK, you can set Worst Q to the Q it uses, but Q's much above 40 is not recommended, IMO. (The bitrate for Q=40 is already only 1284 in this case).
Your previous error: "# AUTOIT - Unknown function/variable!" seems to be gone! The "#Infinity somewhere!" is also gone in 2.4.1
