To decompress them get 7-zip from here: http://www.7-zip.org/
Or upgrade to the latest WinRar.
Recently I've notified about these two products that they use code from the guliverkli project, one of them is free but closed source and not GPLed player (KMPlayer, http://www.kmplayer.com/\), while the other is a fully commercial product (http://www.vx30.com/). There are boundled dshow filters, string, toolbars, dialogs, command line switches, etc..., which can be verified easily by just running the applications and taking a look, or a bit harder by analysing the memory dump. Since I have no better idea about what to do now (I got no reply to the email I sent to kmplayer's developer, it would probably be the same with vx30's too...), I'm posting this as a news here. The developements are going slow anyway because of my job and life, but these cases won't inspire me either.
There is only one rule, don't ask about release dates there :P
Anonymous posts are now disabled in the tracker. Sometimes I have to ask for more information on things and can't do that when the submitter was just "nobody".
If you want to make your own releases without waiting for me to do it in the future, then please create an account here at sourceforge and let me know about it in email, so I can add you to the members list of this project with releasing rights.
