Can I use sound and video on the pages of Flash Version?
Yes. You can use SWF pages with embedded, uploaded sounds and video files in our Flash Version.
To include video, please refer to the sample file (07.fla) in the "Source" folder. The video doesn't have to be embedded on the timeline as I've shown (dynamically loading an FLV or SWF would work fine too) but the key is that the video CAN'T start on the first frame. This WILL cause problems. I'd recommend using the onVisible and onInvisible functions mentioned above to control the video playback.
