vray 2.00004 vs SP1 bug and questions

[QuakeMarine1]

i am facing a strange bug
scene file made maya 2009 VraySP1 renderable cam "camera1"
i open in 2011 VraySP1 - all fine - camera to render is camera1
i open in 2011 Vray2 - render cam is "perspective"
same to 2012 + Vray2

i batch render a super slow camera move from left to right
the image content are more less the same each frame @ 8 min rendertime
some nodes in farm render 4min longer for no reason - the hardware is the very same aswell software
if i restart the longer frames using the same nodes as before the rendertime is 8min
mystery ?

do SP1 vs 2.0 render the same images without difference in gamma reflection etc ?
since the vray core is modified i am sure its not but i better ask

There were some changes to the way the camera(s) for batch rendering is (are) specified, you may want to revisit the V-Ray settings in the new version.
