originally found at rtsp://helix.nfb.ca/oscar/ryan_hv.mov appears to be sorenson and qdm audio in rm file. mplayer detects as REAL format, but cannot find stream. ryan_hv.mov downloaded using windows program NetTransport. quicktime can play the stream but not the saved file. realplayer10 cannot play the stream, but it could be a missing codec problem. (dunno about local file).
