IIS Pull publish point start is not zero (t!=0)

I've two Azure windows virtual machines (VM1, VM2) and I am creating publish point on both machine using Push-Pull.

1. VM1 is for Push (http://vm1.cloudapp.net/PushPoint.isml)

2. VM2 is for Pull (http://vm2.cloudapp.net/PullPoint.isml)

With this scenario encoding is working fine but when I check the publishpoint manifest on browser using:

http://vm1.cloudapp.net/PushPoint.isml/Manifest

http://vm2.cloudapp.net/PullPoint.isml//Manifest

start time of both manifest are different, about 30-40 seconds. So the media start positing is changed. Another thing is that if on vm2 encoding doesn't start immediate, I checked it by reloading above manifest links in browser.

I want to know how can I get the pull video from start? I mean both video starts from same position.

Thanks
