I have a few burned cd's and they are acting funny. When the cd is put in some computers' cd-rom drive, i have to fight with it to read it (by shutting off compuer and restarting, sometimes never works for long time). On other computers I can read it fine the first time. The cd's have been burned for a long time, at least a year. This is very annoying, if anyone knows of a solution, plz reply.
