You have not mentioned whether the Amiga is being booted up from cold, or
is just being reset. With the PAL Amiga if a reset is attempted and any
processes in memory do not release the memory they are using then problems
can occur with the Amiga running out of free memory. Quite often if you are
only very slightly short of memory then the process you are trying to run
will load and run, but will not be able to allocate itself enough memory 
for buffers etc.
This can be a problem with the director, if there is not enough memory
available to load a screen display then the end of the display will be
cut off! I do not think the Amiga is setting itself up as an NTSC model
as only enough of the display is removed to allow it to be loaded.
This problem happens with all the people I know with Amigas, the only
solution is to either swith of before loading Director, or to buy some
more memory.
