This all sounds rather worrying ... i've just shipped a load of stuff mainly books, DVDs and work files - my shipping agent, who I chatted to at great length (they deal specifically with The Gulf) said that it's absolutely normal to ship these things and didn't ask for a list of every title...
From reading your posts - am i likely to arrive in Doha and my belongings to be held up by customs as they go through each and every DVD i own...deciding whether or not it's suitable ...Argh!?

Ps - there's no porn or anything like that... but maybe a few political films - mainly relating to African nations...?
