Nope, H.264 has been designed to allow for more gracefull degradation in 
the face of packet loss. If with HD you mean MPEG2 then you are correct. 
The rest of your post being concerned about H.264 though, the answer is 
no, not more sensitive.
Keep in mind that in the USA, HD at the moment in most cases means MPEG2 
HD. USA will take another year before starting to deploy H.264. They 
will move that way though.
