Censorship

[vipco]

Was just wondeing if anybody knew ( Angel, Vince ) how the censorship laws stand in Ireland.
As im from N.Ireland the BBFC cert is the legal requirement, but some DVD's feature both BBFC and the Irish Censorship Board certs.
What I really want to know is, do the Irish Censor usually just approve the BBFC version or do they review films and rate them themselves, reguardless of any UK version .

I ask as on IMDb , some films you get just the UK details and some give both UK and IRE. details with the Irish version sometimes running longer.

If I took a trip down to Dublin would I find much difference between whats on the Zavvi shelves in Dublin compared to Belfast .?
I ask as I was thinking of going down for a DVD and Game 'shop' and take advantage of the lack of Customs at the boarder.
