Query: Check before you buy

I loved the low cost of purchasing the DVD unfortunately we are unable to watch it. The CD is formatted for the UK which is different than the US. And to be quite honest, not worth the hassle of returning because then the cost of shipping (to and from me) would be more than what I paid for. So, I'm stuck with a product that doesn't work and that I will end up throwing away.Once bitten, won't let that happen again. Check before you buy.....is the product for the US or another country?
