There are several Flash Video features that are available in Flash CS3 but not in Flash Lite 3.0. These features are:

• RTMPT and RTMPS connections are not supported; only RTMP is supported. If you attempt to connect to a Flash Media Server using an HTTP tunneling protocol (RTMPT) or SSL (RTMPS) connection, your connection defaults to an RTMP connection.
• Two-way communication between clients is not supported; only one-way communication is supported in Flash Lite.
• Multiple Flash Media Server connections are supported, but may be of limited use on mobile devices due to device limitations
• The recording of video is not supported in Flash Lite.
• Alpha channel video is not supported in Flash Lite. The On2 codec used for Flash on the desktop supports an alpha channel, but the version used for Flash Lite 3.0 does not.
• The FLVPlayback component is not supported in Flash Lite 3.0. See About components in Flash Lite for information about components.
• The ActionScript Camera class, which is used in the desktop version of the Flash Player to connect to a user's local camera and broadcast the video, is not supported in Flash Lite.
