I went to the mplayer site but it is all a bit daunting for me, though from what I can see the files are dated 2006 so unlikely to be more recent.

Also I tried to install Media Converter 1.42 and 1.43 on my XP computer but it won't run. The terminal window flashes up, closes down and that is it.

I think I am a bit of a dead loss on this subject but thanks anyway.
