RMS only powers the "video recorder" and "A/V chat".. all the other widgets don't need it at all. My first guess is ffmpeg.exe because it seems the video is uploading correctly, after that the next step is for ffmpeg to convert it to an flv. Is your ffmpeg.exe set to "777"? Also, you said your host said it could stream movies and music but you might have to ask them if they allow executables to run. I was helping a guy two weeks ago and he ended up having to swap hosting see more companies because that is what the problem turned out to be.
