help transfering pictures from comp to CD-RW

I have done it before, dont know why it's not allowing me to do it again. They are different type of cd's I had Memorex now I have Sony. The Memorex was high speed 12X 700 MB 80min and sony is 700MB 80 min 1x2x4x Would that make a difference?

I cant even copy anything from excel or word.

Dell dimension E310
504MB 2.80 GHz

 

Do you have any other brand of disk that you can try??

 

I put the memorex in and added a video clip, it just worked, but now when I go to put the Sony in, still says the same thing "its not a writable CD or that it's full please put in a new CD" It's not full they are brand new.

 

My CD drive doesn't like Verbatim brand but everything else.....I would say yours is the same for Sony brand

 

Great thanks

 

I tried Maxwll, memorex and sony cd-rw and dvd-rw and my computer keeps telling me the cd is not a cd -r or cd-rw ugh
