Weird quicktime problem. Help!

I have embedded a quicktime slideshow on my blog which is on the front page at https://www.chrisfawkes.net

There it plays fine though this is just my domain address. The real address for that page is https://www.chrisfawkes.net/blog1 but if you go to that address the quicktime will not play. The poster image shows ok but when you click play the ? symbol comes up.

I am at a loss as to why. Could someone explain why and what i can do to make it play on either address.

Thanks in advance.
