the host makes no differnece
I think you are expecting Dreamweaver to be running the php code and then showing you the page
I do this by installing one of the 'wamp' packages e.g. xampp which lets you run your own machine as a web server
I'm not sure if latest version of DW does this for you - but that's the thing that is needed - otherwise you will see the code but no finshed web pages
an alternative is to upload to your actual webserver and preview there, but I dont recommend that as it's a long winded process
