Flash Player for IPTV in Flash Media Server [2010]

Hi,

There are three video sources.
1- educational videos on the system that can be played on demand. (VOD local)
2- streaming videos available on different websites that can be played on demand (VOD remote)
3- IPTV live streaming videos

videos from three sources have to be played within single flash player that we need to design.

For the two VOD types, we have to provide the pause and play functionality.
For IPTV, pause and play is not required, However, channel switching time is critically important here. The user should get the program behavior as close to TV experience as possible. This means channel switching should be fast. To provide this, buffering of video is required for multiple channels.

Please provide some tips on how is this possible in Flash Media Streaming Server 4.0 and if there is a cheaper solution available to do this on.

Thankyou,
