I have installed Suse 9.2, Ubuntu, Mandrake 10.1 and Yoper. Is there anyway of installing the packages that are on the Suse DVD (for example) onto the other distros?

I have managed to install a few things manually but problems arise with 'dependencies'

The reason I want to do this is because each distro has it's own unique problems. Originally Yoper wouldn't recognise my soundcard but then I found something on the Mandrake DVD that worked a treat. As of yet only Ubuntu can play CDs (actually they all appear to play them, but there is no sound), I've managed to play Mp3 files on all of them apart from Mandrake which can play them but at a faster speed and therefore higher pitch. Ideally I would just like to set up one distro as a main os (probably yoper). Ubuntu will only display 600 x 480 so the windows are bigger than the monitor, and suse has a variety of problems...

Anyway suggestions would be greatly appreciated.

Installing programs from the SuSE DVD isn't going to fix hardware detection.
You'll be lucky to find a Linux distro (or even Windows release) that detects all of your hardware out-of-the-box. When I installed Ubuntu, my screen resolution was off, but it was an easy fix. When I installed Mepis, my sound wasn't working, but that was an easy fix as well.

I'd say if you can find a distro that detects everything except one thing, go with that and work out that one problem.

Simple as that.
Why don't you choose one distro and tinker it to the very end until you're fully satisfied with results. Running from problems won't solve them. Gather some patience and wrench one distro of your choosing

I totally agree, and that is pretty much what I've been doing with Yoper.
I was wondering is there any way to find out which program or driver is responsible for making the cdplayer work in ubuntu, so that I could install the same driver/program on yoper?

Also I am able to play some dvds (much to my suprise and delight) but not others, the screen is blue or mutli coloured interference any tips?

with SuSE follow this manual

and you'll play the kitchen sink
