VSO Downloader FAQ
If nothing shows up in your download list:

- you may have launched VSO Downloader after the video/audio has begun. You must start the program before playing the media so that it detects streaming from its beginning.
- the media has been stored in your browser's cache. Media which have been completely loaded are stored in the cache to enhance data loading. Click here for a brief tutorial on how to delete the cache.
- your could firewall is preventing VSO Downloader from capturing the media file.  Desactive it and view a new video/audio file to see if this corrects the problem.
- the media must be encrypted in a format that is not supported yet.


Here is a list of some of the sites VSO Downloader users have reported VSO Downloader is working with. Listing all of the sites is impossible as the downloader can detect streams from sites we are not aware of. Currently, we do not RTMP-, RST- and ASF-encrypted media streams are not detected. Refer to the above point if you get no media detected.

Nothing but an internet connection and a Windows Operating system. VSO Downloader is a stand-alone program. It is not installed in your internet browser, it just works with your internet connection.

Most streaming video formats like FLV or MP4 can start at any position of the file and are considered as a new video each time you seek it.
When you refresh a page you can have 2 cases:
1) the video restarts at the previous position so it is considering as a new video and will be downloaded again
2) the video restarts from the beginning, in this case it should not be downloaded
VSO Downloader downloads what you are watching, i.e: it can't know the beginning of the video if you start to read it from the middle.

We recommend using VLC media player, it will play most of your files. Download it here.

This happens when a file already exists with the same name in the output folder. Some sites will display the same file name when downloading (for instance, on youtube, name is: videoplayback.flv), so you may rename them to avoid confusions.

It may be a file hoster restriction. Some servers won't allow simultaneous downloads. You must wait for the current file to finish downloading.

See this post for some converters.



My download status is 'error':co
Right click on the file in VSO Downloader and select "View file log". Errors should be in red. Here is a non exhaustive list of errors:



Some sites generate random URLs for each file. It means the file will change of location at some point, though still being hosted on the site. This problem may be linked to the 'limit exceeded'.


The server may limit the access of the file to one hit. When you click to download a file, it counts a hit. For instance, megaupload limits the number of hits on each file, so if you try to restart the download, this error is likely to show up.



The downloader couldn't get the whole file. FDataCount = file size you have downloaded. FPartSize = total file size.


When a file stops downloading for a while, it is likely to be a socket timeout. (speed will fall to 0). It means the server has stopped transferring data. It could be either on purpose or a momentary problem coming from the hoster.


The file hoster has restricted the access to the file. Download limitation or anti-leech measures may cause this problem.
