That is not the only difference. When people use the terminology correctly and follow the distinctions correctly, we also see that media streaming is fully seekable while progressively downloaded media is not. Also, they have different performance characteristics under low bandwidth conditions (see below).
For that matter, both progressive download and streaming allow storage of the media to the local hard drive; the difference is that in the latter, it is never available all at one time, so it is harder to steal the IP. http://en.wikipedia.org/wiki/Progressive_download#HTTP_Progressive_Download_versus_Streaming_Media has a pretty good summary of the difference. The summary at http://www.dncompute.com/blog/2006/05/04/flash-video-streaming-vs-progressive-download.html mentions the superior support for seek in streaming, but since it is from an author with a bias for Adobe, it is a little suspect. But only a little.
