I have 3 versions.
The first version is being used here and there.
Second version is exclusive.
Third version uses drm as microsoft cleverly decided to block popups on everything BUT drm
So if your curious about how to do this, i would use the third version right now as its very easy and here's how you do it..
First your going to need a drm service.
Then your going to open windows movie maker and make a 5k movie.. Like basically dont add any video just add an image or something ery small.
Encode the wmv you have created with your drm client.
Embed the wmv file to play automatically in a corner of your webpage ( rename the wmv file to .asf )
This method is great for 404's and things like that..
If you want custom code, it will be site orientated , so i advise finding someone suitably qualified..
ICQ me and i will recommend someone. I have alot on my plate.
