Shipping Rates

Hi

I'm new to zen cart and I would like to know a way to calculate shipping rates based on the following criteria.

I have two product types - DVD and Magazines
For each product type there is a shipping rate based on the zone.

eg: (for a DVD)
if shipped to US shipping rate per item is $5. if shipped to UK then $10 per item

(for a magazine)
if shipped to US shipping rate per item is $2. if shipped to UK then $3 per item

that means
if 2 DVD's are shipped to US the shipping cost is $10.
if 3 DVD's are shipped to the UK the shipping cost is $30

if 2 magazine's are shipped to US the shipping cost is $4.
if 3 magazine's are shipped to the UK the shipping cost is $9

I can create zones and give them a fixed value per item to calculate the shipping cost in zen cart. But I can't find a way to incorporate product types,zones and price per item together.

Please help.

Thanks
tbt
