I have noticed that many people have been complaining that Downtube 2.1 sometimes do not run correctly in many computers because of the absence of  Wget.exe.
If you have such a problem, download Wget here http://users.ugent.be/~bpuype/cgi-bin/fetch.pl?dl=wget/wget.exe
Then copy it to C:\Windows folder or to another folder where Windows is installed. Follow the same procedure if you use Downtube in Wine/CrossOver Office.

Otherwise, if you want to grab the version  with bugs corrected or even the program as a whole,  go to Downtube 2.1 Full in http://downloads.sourceforge.net/downtube-gui/Downtube21-FULL-English.exe?modtime=1171118302&big_mirror=0
For the time being, I am having difficulties in placing this program on the Internet due to some problems in the server of ftp in the CódigoLivre and  also on my Internet. If you are a volunteer to host the program in some place, I would like to contact you personally.

Second Test Version of Downtube 3.0 for Linux has been released.

ChangeLog
downtube-batch: additional script for downloading bundled videos only once. It is in testing phase and is intended to be coupled to the main program when stable.

Example
$ downtube-batch videos.txt
*connection via proxy: proxy allowed for downloading videos

Initial conversion setup: called “presets”
complete translation: two available languages for the time being: English and Portuguese.
This was carried through using gettext (), that brings two benefits:
- Downtube is now capable of automatically detecting the language of the user and capable of loading the translation.
- new languages can easily be added, only translating the file
downtube.pot – that contains the original strings (in English)- into the new language, using a tool (KBabel, for example)
file names: downtube saves the files with the same names of the video hosted in youtube.

Default directory: a default folder to save videos in.
Encoder and player: ffmpeg pack (ffmpeg encoder and ffplay player)adopted as default, due to easy installation handling.
All options are visible by entering “downtube -h” in command-line.

downtube 3.0 beta 2 – 49kb

The DreamLinux Project and the Downtube project are now partner projects.
This partnership may allow the development of Downtube GUI (Front End) for Linux among a series of other advantages for the two projects.

This may also mean an entrance of the Downtube project for the Linux world and thus we may count on the contribution of the users of the community.

Downtube 2.1 is already available for installation in the “Easy-Install” of  DreamLinux. The Link to downloading for the “.deb package” is [download DT GUI]
If you want to download Downtube GUI ( Front End) for Linux made in Ruby, click here.

To install Downtube GUI (Front End) for Linux, check if “libgtk2-ruby package” is installed, since it is a dependence of Downtube GUI.
