I have noticed this problem too. I have an application that reads and writes
tiled planar files using libtiff, without any problems at all. As you say
though, tiffcp does not work with these files, and interestingly enough
neither does xv. I haven't done any work to figure out why.

My application reads and writes an intermediate file in this format. I can 
easily use it to translate existing files, so if you are interested let me
know and I'll send you some. I believe that, despite the problems with tiffcp
and xv, my files are correct because I can read them successfully with
libtiff.
