Firstly hello all, am new here

had an amiga during the early 90's and decided the othe day to get her out again and see what happens.
I've been playin through some of my old CD32 games but also have got my hands on a few of the iso out there. As is mentioned above in the thread I too am having serious trouble buring anything and getting it to work. It appears that games of a few mb in size work fine but anything bigger always fails.
I've used Nero, Alcohol 120% and ImgBurn with exactly the same results in each. The majority of games just sit on the amiga cd32 screen and finally after 10minutes dump out into a workbench with some random error.
Could my problem be that my old machine is on its way out? Or is it just that she was built before the days of CD-R's and the drive don't like them with to much info on.
Any advice would be great. I can always just use WINUAE but would rather be using the real deal.
P.S. Sorry for the long post.
