First of all, you need to answer that what channel is used to communicate over the network between client and server. second, I guess as your expecting the flash content, then the channel should be RTMP over TCP OR RTMP over UDP. I guess LR.11 supports RTMP over UDP. Therefore, once you clear with this, then also I doubt that Run Time Viewer will be able to fetch the response of Flex/Flash content. You need to investigate the AMF /RTMP calls through the tree view response during replay.... Hope this info would be helpful for you.
