glad to hear the code worked twice!
regarding saving to dvd, impulse has an archiving feature. click the 'globe' (it's either the SD or impulse logo) in the top left corner. in there you'll be able to set an archive folder.
then right click the app and select archive. this affectivly turns it into a 7-zip archive with some differences and the file's named *.impulse.
you can then copy that file to another computer and using impulse on that machine, install it.
for some reason the archive is only for the same operating system, so say you create it on XP you can't use that *.impulse file on vista.
to get round this you need to select download and archive (again in the 'globe' somewhere') this archive will have all the files needed to install on different OS's.
hope that helps
