Both RM Recorder (http://all-streaming-media.com/record-video-stream/WMRecorder-One-click-online-audio-video-stream-recorder.htm) and Net transport (NetXfer) (http://all-streaming-media.com/record-video-stream/NetXFer-Saving-Windows-Media-Real-Audio-Video-QT-streaming-to-hd.htm) can record RealMedia streams without problems, if rtsp is enabled. Unfortunately, in my company network, the only protocol allowed is http (rtsp and mms - disabled), so I tried to use http instead of rtsp. For example, RealOne Player can do that, by the following setting:
Tools->Preferences->Connection->Network Transports->Manually configure connection settings->RTSP settings->Attempt to use HTTP for all content. But I don't know how to "convince" RM Recorder or NetXfer to use http instead of rtsp.

The stream URL is (for example):

rtsp://212.54.100.33/video/DATA-2006-04-14-22-01.rm

In NetXfer, and also in RM Recorder, I've tried the following URL's:

http://212.54.100.33/video/DATA-2006-04-14-22-01.rm
http://212.54.100.33:8080/video/DATA-2006-04-14-22-01.rm
http://212.54.100.33:80/video/DATA-2006-04-14-22-01.rm

But it did not work. In the corporate network, we don't use proxy. In RM Recorder (URL mode), I've tried even the "mirror" mode (which must record in parallel with RealOne Player), but still don't work. RealOne plays fine the stream (through http, of course), but RM Recorder cannot record it.

[Stream Recorder]

First of all before using any stream recorder (http://all-streaming-media.com/record-video-stream/all-streaming-video-recording-software.htm) you need to get a stream URL (you may skip this step when using WM Recorder and RM Recorder). To find the URL use URL Finder, URL Snooper or Packet Sniffer software (http://all-streaming-media.com/find-stream-URL/URL-Finders-Packet-Sniffers-URL-Snoopers-Software-to-Find-hidden-stream-URLs.htm) like free Project URL Snooper (http://all-streaming-media.com/find-stream-URL/Project-URL-Snooper-Find-the-actual-stream-URL-Free-download.htm) (some stream recorders (http://all-streaming-media.com/record-video-stream/all-streaming-video-recording-software.htm) like WM Recorder (http://all-streaming-media.com/record-video-stream/WMRecorder-One-click-online-audio-video-stream-recorder.htm), RM Recorder, Replay A/V (http://all-streaming-media.com/record-video-stream/Replay-AV-capture-Streaming-Video-Audio-Radio-Shows-Online-TV-Broadcasts-Video-Clips-Audio-Archives-Podcasts-Free-to-try.htm), GetAsfStream (http://all-streaming-media.com/record-video-stream/record-streaming-video-windows-media.htm#GetASFStream) have a build-in URL finder).

Just play your stream and use any Packet Sniffer and URL Snooper software to find a stream URL. It is very easy.

After that you usually don't have to worry about changing protocols and ports manually. However if you like to do it manually you may try RTSP port 554, PNM port 7070 (also known as PNA port) or HTTP ports 80 and 8080.

I also suggest you to learn more about RM Recorder (http://all-streaming-media.com/record-video-stream/rmrecorder-save-Real-stream-to-disk.htm). It has a very nice user guide which is easy to follow.
In the majority of cases it can record audio/video stream that your Real Player plays. Just try to play with Proxy and ADA mode. If it can't record some stream, please send the URL to me or directly to a developer.

Actually, I think the corporate firewall blocks port 554 (used by rtsp) or the rtsp protocol. So, I found the solution: using the 8080 port (used by http) or using the port 554 (used by rtsp).

Instead of the URL:
rtsp://212.54.100.33/video/DATA-2006-04-14-22-01.rm
use:
rtsp://212.54.100.33:8080/video/DATA-2006-04-14-22-01.rm
or
http://212.54.100.33:554/video/DATA-2006-04-14-22-01.rm
and it should work great!
