.m4v playback not working on iPhone 3G

I just posted this in the QT forums as I didnt know where this would be applicable but thought there might be someone in the iPhone discussions that could help:
An interesting problem that I havent been able to reconcile through my hosting company so I thought I would post here. I exported a video clip using QT Pro, export for web and uploaded the entire directory and tested for playback on my iPhone:
http://propeller-group.com/Hypnotist/ReadMe.html
(iPhone playback doesnt work and it does not even load the poster image - desktop playback works btw.)
Then I proceeded to upload the same directory to another site to test for playback:
http://mattlucero.com/Hypnotist/ReadMe.html
(both playback methods work perfectly)
So then I proceed to see if the individual files are even playing back on the server that wasnt loading the video on my iPhone:
http://propeller-group.com/Hypnotist/Hypnotist-iPhone.m4v
(now it is playing back fine on the iPhone when hit directly)
This leads me to believe it is an html/scripting error of some kind? But this is the exact same html file generated from QT that has been uploaded to both servers. Why would it work on one server and not on another? Is there possibly some issues with the server not being able to interpret the reference file correctly? Or is there something else I am missing? A possible phone issue? I have tried configuring MIME types using a .htaccess file, but I am not sure if this is even the issue as I am able to play back the video fine when hit directly.
Any help would be greatly appreciated.
Thanks!
