Well, to answer your last question first, games frequently resync the monitor
to have more clock cycles available for other stuff.  If you run some games 
(or demos, which also often do this) at 60Hz (USA standard), they slow down 
tremendously.  Now, to my understanding, european monitors default to 50Hz.
Thus, you need what is called a 50Hz Booter.  It is a small program that 
runs, then tells you to insert the disk to be booted and press a key.  The 
Booter then reboots, but leaves the monitor syncing at 50Hz.  If there is 
not such a booter on atari.archive, I can post one there.  I can also email
you a copy, if you like.  

I do not know if this will work on your televison, I have never tried it.  I 
would imagine that it will though.
