Thanks for the su tip -- have done that and the "Multimedia" script worked. It didn't do what I wanted however! My situation is that I have RealPlayer10GOLD.bin on my usb thumbdrive /mnt/sda1, and every time I reboot my machine if I want realplayer to work in Mozilla I have to (re-) install the realplayer via:

# cd /mnt/sda1
# su
# ./RealPlayer10GOLD.bin

What I was/am after is a method of having realplayer available without having to re-install it all the time, and running this Multimedia script looked like a good solution. What I have just tried (after trying lots of stuff and it not working) was to go to the log file created when I install realplayer, for me this file is "/mnt/sda1/RealPlayer/install.log". Scrolling down this file I came to a line "post-install setup commands:". Every line below this point I copied into my Multimedia script file. (There were about 200!) I have just tried running this script, and so far give it a partial success -- there were no complaints from running the script itself. When I tried in Mozilla to view realplayer content, it whinged the first time (something about not having realplay, hxplay or something on path), but I clicked on the content a second time and it worked fine! (Computers eh? - I'll never understand them!) So, maybe this will do the trick -- but I would be interested to hear of any more elegant solutions, especially one that doesn't require a script so long!

Cheers,

Rob.
