Thanks Dave for your valuable suggestion.
I did create 3d video file with side by side with half using sony vegas 10 and copied this file to USB pen drive.
I connected this USB to Samsung 3D tv and able to watch this file in 3D by selecting side by side 3d format using remote.
Same USB I connected to Sony 3D TV and not able to watch it in 3D.
Do we need to encode diffrently for Sony 3D TV ?
pl advice.
Thx
Kiran
