easy way to read individual VOB files?

[Chad Leigh]

We are flying to Japan shortly to visit my wife's family.  We bought  
one of those portable DVD players for my son to use on the long long  
trip over there.  I am wanting to make a bunch of DivX, or however it  
is properly capitalized, files so as to avoid bring original DVDs on  
the  trip.  I would like to not include the stupid stuff and want to  
include just the main feature VOBs.  (No worries, DVDs are not  
protected).

How can I look at the individual VOB files on OS X?

Thanks
Chad
