Ok the failure was indeed media related. It was able to finally write a SONY 2X 25NH BD-RE successfully both movie and Data, So now I know its my Drive problem albeit is a stupid drive that doesnt seem to support a whole lot of media formats.
I was trying a Verbatim BD-R LTH Version 1.2 and a SOny BD-R 6X Version 1.3. It seems this Drive only supports Version 2.1 and above as the Sony I have got is version 2.1 BD-RE.
The problem is there is no documentation and repeated fight with HP and No Help from LG it finally turned out to be the media.
Thanks for your help anyway and its indeed a nice intelligent software you have there.
Thanks a Lot.
