Im having a lot of issues with safari when i preview my video background page. I assume that the video needs to fully download before it will play? My video is only 6MBs, but each time i refresh the page, it either

1. hangs on the loading animation,

2. shows either the black BG with the angled pin stripes and just hangs, or

3. it will show the buttons and text overlay for the slider...but still no video.

Chrome seems to be ok as Im using a WebM file. Can safari use the web file?

Can youtube be used as a background video?

Thanks
