You weren't partially, but mostly right

Guess i should leave that for the experts:
All DL DVDs:
Rainbow Six - Vegas: mounts fine as ISO and B6I...
C&C Tiberium Wars + Splinter Cell 4: B6T doesn't mount, no matter which profile

Concerning 1.1.3.0:
Andareed advised/gave me that version when doing some tests with Securom CD using cooked ISOs + BWAs (btw. this works just fine);
don't know whether it's final/public
