介紹：
Real7ime Converter (R7C) is a converter of any RealPlayer streaming medias
(video and sound) to AVI/WAV/MP3 format. It is a realtime converter because
it does not manage Real Time Streaming Protocol(tm) (RTSP) directly so the
needed time to convert a media will be greater or equal to the time of the
media.

Features:
---------

* A cool user friendly GUI

* A preview using DirectX 8.1 or later (no preview sound definitively
because R7C is not a player)

* A MP3 encoder

* The last but not the least, a URL fetcher which can get all, yes *ALL*
direct link to any played video of RealPlayer on the web!
