Replay Media Catcher and
WM Recorder are very different. It is probably easier to try them to find out why.
While both RMC and WMR can download
- Flash audio and video streams (HTTP and RTMP)
- Windows Media streams (HTTP, RTSP, MMS)
- Real Video streams (HTTP, RTSP)
- QuickTime streams (HTTP)
they do it differently (because they've been developed by different people). Until recently WMR had a very weak support for RTMP flash videos streams, while RMC became very famous because of its ability to record such streams. WMR support of RTMP protocol has improved significantly since version 14.2.
WMR is a legendary software. It is the most powerful Windows Media stream recorder. It is well know for ages, especially for being the most powerful Windows Media and Real Media stream recorder. Also it was the first easy to use streaming media recorder, which required you to hit the record button only to start recording.
RMC has its own strong points. Its Video History Tool allows to capture HTTP packets from flash player (rather than download them). It can also record any sound from your audio card even if you don't have Stereo Mix / Wave-Out Mix. It can extract MP3 files from flash videos that use them (for example, youtube .flv videos), so you don't lose any quality when converting FLV videos to MP3 with it. Also RMC can convert audio /video files between the most popular formats and add converted files to iTunes. Another really nice feature of RMC is that it can rename videos automatically, plus it can identify music tracks, tag and rename them automatically.
