Sticking with the multimedia theme, TransKode is a front end for
the highly flexible, modular command-line toolset Transcode, which
is one of the most versatile audio and video-converting tools
"Transcode has both a graphical and a text-only interface and
supports a vast number of formats including DV, Mpeg-2, Mpeg-2 Part
2, H.264, Quicktime, AC3 and any format included under Libavcodec.
Transcode can import DVDs on the fly and record from Video4Linux
This is one of those brilliant little pieces of software that you
won't be able to live without once you've sampled it. Giver allows
you to drag and drop files to users on your network. It will also
automatically detect other Giver users on your network."
