Samsung SH-S182 can't figure it out

Hi guys!!!

I am a newbie!!! yes I am always with a problem because i don’t know… I have an Acer Travelmate 2350 and I bought an external dvd burner Samsung SH-S182 ,the computer reconizes it, but i cannot burn anything… i used these dvds:

DVD+R VERBATIM 1X-8X
SONY DVD-RW 1X- 2X
DVD-R STRATHFIELD 16X
DVD+ R SKY PRO 8X

i TRIED TO PUT THE CD TO INSTALL IT, BUT IT DOESN’T DO ANYTHING, JUST SENDS ME TO THE SAMSUNG WEBSITE…

Anyone knows how to do it???

And another thing,… when I use my nero 7, what option should i click onto, when I want to burn dvds , that I have in my harddrive that I stored with DVD SHRINK… thanks a lot guys, really appreciate
