Answer 1

Don't bother with regular expressions when they aren't needed...

function checkVideoUrl(url)
{
    return url == "http://www.56.com/u96/v_NTQ5MTM1ODE.html";
}

Answer 2

Assuming v_ indicates that it's a video URL:

/http:\/\/www.56.com\/\S+\/v_([^\/]+).html/i;

This will also capture the NTQ5MTM1ODE part, which is probably the video ID.
