weird thing is, that its a regular HTM file, which is linked to 2 SWF and an FLV file. plays fine on my local version, and played fine on the previous server....
I found that the swf video players provided in dreamweaver quit working at JH following the last update to Dreamweaver CS3. They work great on my dev boxes, by not at JH. I found the best workaround, in my case, was to create the player in Flash CS3 to call the flv and drop that into the needed page.
Works great.
I store the flv's over at Amazon using their s3 service to reduce server load at JH.
