On Blip.tv I can't even download the video: http://blip.tv/framatube/110225-conf-e-moglen-navigating-the-age-of-democratized-media-5815072

Linterna Magica says it's buffering and nothing is happening (see screenshot)

Right clic on the top icon download a silly link: Potatono-OOPViews677.mp4 that's 37kb

which has nothing to with the link that you can copy from the contextual menu http://blip.tv/file/get/Framasoft-k110225ConfEMoglenNavigatingTheAgeOfDemocratizedMedia669.webm

Yet wget -c http://blip.tv/file/get/Framasoft-k110225ConfEMoglenNavigatingTheAgeOfDemocratizedMedia669.webm

returns "Not Found"

Building from svn is not mandatory. The svn daily builds [1] in the downloads area are meant for newbies. ;) As Savannah mirrors are updated at 24 hour intervals the direct link should be used for downloads to ensure that the latest revision will be used. Daily builds are automatically compiled at 00:30 EEST/EET and manually just after I commit important fixes in trunk or the stable svn branch.

You are right about the svn command. It is nowhere documented, as building from svn is rare for most users and doing so it is highly possible that the user already knows what svn is and what should be installed. I might add few words on that.

Installing by hand is not recommended. Though, I do it for convenience too. I can't comment on the issue you had, because I don't know what exactly happened. I always try to explicitly overwrite the file already installed instead of just coping in the directory, so I do not end up with two or more copies of Linterna Mágica running at the same time, if at all possible.

The required packages for building are listed in the documentation. [2] Are you saying that it is not clear that the tool ls (and others) from the GNU Coreutils package is needed?

The compiled userscript is executable just for notification (for terminals with colors) and as a joke/hack. :) It is not required for anything.

I think recent Greasemonkey versions are handling capital letters and accents.

Thanks for testing. Please, report any issues with this fix. I guess next week if stable enough it will be merged to the stable branch and new bug-fix release will be available.

Many thanks, Ivaylo for the svn. It works fine on youtube movies. I tested the Potemkine film. I'm going to test it as much as I can.

Perhaps, you could add a few things in the documentation on SVN for SVN newbies:

You should clearly state that make, for instance is a package but ls, for instance is a tool included in a package (so basic that is probably included in any distros)

Most of us will need to install package svn — otherwise we can't execute:
  svn co svn://svn.savannah.nongnu.org/linterna-magica/trunk linterna-magica-trunk

The command make did the job. As I'm running Firefox Beta, I copied the file linternamagica.user.js to ./mozilla/firefox/xxx.defaut/gm_scripts/linterna_magica

In Firefox, the script didn't appear in > Extensions > Userscript.

Yet, the file linternamagica.user.js is executable.

So I tried installing the script from the browser. I opened the
linternamagica.user.js (Ctrl+O), the install box appeared, and the installation went fine.

Linterna Magica works yet the folder ./mozilla/firefox/xxx.defaut/gm_scripts/linterna_magica is empty.

This is pure Magic. Perhaps the script is read from the linterna-magica-trunk folder?

So I'm going to start the installation into Firefox again.

The interface is displaced for clips that YouTube displays as unavailable for unknown reasons. The clips play with Linterna Mágica. A CSS fix is needed.
