This is true Biju. What I am saying is that edge pels should be extended
from line 241 rather than line 255 for the image resolution described. 
My understanding of the standard is that the decoder can not treat a 352x256
and 352x242 in the same way when extending the boundary.
I have a concern with this as our (vhdl / fpga) decoder successfully passed
the compliance tests even though it did not (in my understanding) support
this case correctly. 
This being the case is the coverage of the conformance streams really
adequate ? There are several other similar cases which cause me concern. I
would be interested if anyone else has found possible holes in the
conformance tests ?
Your's waiting to be corrected,
