question about PSX backup's and CD writers

[bobbye]

Sorry, other questions keep poping from my head after I wrote
a few of them, please forgive me if I have taken 80 % of this thread but I am new to this and I want to learn a little with your
great help.

I forgot to mention 2 things - I started to download psx game images from the playstation image newsgroup - I want to ask
if I only need to write the image (which was prepared by someone else, maybe with a good cd writer and with better
experience), can I do it safely with my Smart and Friendly cd
writer ? or do I need those best writer (as I mentioned in the
above questions) ?

Also, I downloaded a couple of games before I got my psx, and I
burnt them X4 to some cheap cdr's - none of them are read by
all the psx's that I tried, would I be able to read these
cd's back to images and write them to better quality cd's (or again
do I need the DAO raw cd writers to do that?)

Again, guys/and girls thank for all your great help :-)
