[RTSP, MMS, HTTP protocols] - ASX Recorder FAQ

Windows Media Streams:

• .ASF
• .WMV
• .WMA

Windows Media metafiles (redirectors):

• .ASX
• .WMX
• .WVX
• .WAX

ASX Recorders allows to download streams like ASF or WMV from ASX metafile and save it to hard disk as a file. Some Stream Recorders allow to save only Streaming Windows Media (which you probably watch using Windows Media Player). Other Streaming Video Recording Software allows you to download not only Windows Media Streams, but also Real Media Streams (Real Video and Real Audio, which could be played by RealPlayer or RealOne Player).

RTSP, HTTP, and MMS protocols are used for Streaming Windows Media (Starting with Windows Media Player 9 Series, Windows Media Services 9 Series and Windows Server 2003 RTSP Protocol is now the default protocol for streaming Windows Media).
Some Streaming Media Recorders can automatically rollover to different protocols (if protocol rollover is supported by the server and switched on). RTSP protocol is supported by few programs like HiDownload and StreamDown. Due to RTSP protocol rollover problem in many cases Streaming Windows Media couldn't be downloaded by old software. So please download the latest versions of Stream Recorders supporting RTSP for Streaming Windows Media before asking a question.

Note that some Windows Media Recorders like WM Recorder can make ASF file seekable. If yow want to make already downloaded ASF files seekable, repair, join or split Windows Media, converting ASF/WMV format to AVI, ... please visit faq-fix-broken-windows-media.htm.

  • Web,

  sites (up to 500 simultaneously) at the highest possible speed.

  While I've been using Offline Explorer as an offline browser for years, I do not consider it as the best program to record streaming media. It has too few features to be a good stream recorder. Though it could be very useful for some specific purposes. For example, if you need to download a web-site with a huge number of small media streams. I used it to download hundreds of pages from an educational web-site containing dozens of audio streams. No doubt it was the best alternative.
  
  OS: Windows 98/me/NT4.0/2000/XP.

  to derive links.
  
  Disallowed characters are NOT removed from filename. So while saving file (especially when it's added after postprocessing), don't forget to check its filename for disallowed characters (i.e. don't use symbols like ':', '/', etc. prohibited by your filesystem). Otherwise you won't be able to save the file.
  
  StreamBox VCR does not work with password protected streams.
  
  While using SVCR it crashed several times damaging my incomplete downloads.

  Streambox VCR allows to resume the recording of an incomlete stream.
  
  Streambox VCR can record Windows Media streams (HTTP, MMS, but not RTSP) and Real Video/Real Audio Streams (HTTP, PNM, RTSP)
  
  Streambox.com no longer distrubutes its streaming video recording software. Streambox VCR could not be used legally in the US. Illegal version could be found with AstaLavista or Google.
  
  Remember that downloading software from unknown sources could cause problems to your system. If you still want to download the illegal version we recommend to use Outpost Firewall and a good antivirus program to protect your computer from viruses, spyware and also from hacker attacks.
