In order to watch the transmission in Linux you need Mplayer program and live.com library. Information about the download of these components you find here.

It is also necessary to download RealPlayer9* codecs. You may find them here. When downloaded you have to extract them in a new directory (e.g. /usr/lib/win32) and during the configuration of Mplayer add an option --with-reallibdir=/usr/lib/win32.
