I installed RealPlayer as it plays streaming video better in Firefox
for the UK news on BBC.co.uk. In windows i found it worked well in
firefox and same on ubuntu in firefox. Mplayer worked but very slow to
load. Even carefully reading the instructions i didn't approach
getting streaming video to work with much confidence. I also have a
couple of classical music websites that require RealPlayer to play
files. I couldn't get any of the other video apps to work.

But i couldn't get the helix version to work for streaming video?
