Drop Outs On Cdr's, why are my cdr's not reading properly?? Options

[alidee]

Can anyone help with some tips for preventing drop outs on cdr's? I am having trouble with cd's burned in itunes not reading properly in other machines..but other musicians i know manage to burn cdr's on a similar set up to mine without the same problem and I don't know how to check to see if its my cd writer or what else it might be...
