Delphi 7. MMS\RTSP downloader(repost)

I need Delphi 7 component that will download videos from RTSP:// and MMS:// streaming protocols to a file on local PC. You can create class or single procedure. Input parameters are URL and Filename. Also I need event for progress bar front-end if possible and "Abort download" feature. FYI. There are many open source projects in C++ over the internet that do this job. As far as I know even "mplayer" does.
