[X4U] DVD regions issue

[Jan Melichar]

As part of some teaching material I am preparing I have to look  
through a wide range of films and it's most convenient to look at  
these via DVDs. Many (well some anyway) are only available as region  
1 DVD which means a switch on my region 2 mac. The system provides  
for a small number of changes of regions which is not much use to me.  
Can anyone suggest a way round this short of getting a separate  
regions free DVD player?
