Firefighter recuritment dvds / cds

[Northern200]

Hi
I have been applying to fire services up and down the country for the last year and have not getting any progress.

For people who are already in the job or who have used these DVD/CDs what are your opinions on them?

Would it be best to visit numerous fire stations and ask for help?   Or is it also a good idea to buy one of these DVDs?

Thanks
Andy
