Seeing DNS changes takes too long on my PC, can it be my router misconfiguration?

dns

I administer a few sites and need to update their DNS entries from time to time, e.g., adding an A-record point certain subdomain to a certain IP.

When I check sites like http://www.opendns.com/support/cache/, I can clearly see the DNS change taking effect throughout the world - is it just my PC that can't see this change (ping newsubdomain.example.org says it cannot resolve host name)

The network "map" is like this:

My PC -> my router -> my ISP's router -> internet

On my PC, the DNS is set automatically which means that if I run iconfig /all, my router will be returned as the DNS server (192.168.1.1).

On my router, the DNS is set to be what my ISP provided me with.

Is this correct? What can I do to see new hostnames resolved quicker?
