The read by "dd" on the remote side isn't reading 1024K most likely,
so when the third record rolls around, it writes some odd amount.

Try the following -

dd bs=1024k if=/dev/rmt0 | \
	remsh HostWithTapeDrive 'cat | dd ibs=1b obs=1024k of=/dev/rmt0'

I've used this in the past on random collections of AIX systems and it
works just fine.
