Newbie Can't Burn

[cheatengine]

I grabbed 102 Dalmations and Bomberman from the isozon site.
I tried to just DiscJuggler to burn each CDI file using the "write and verify" option.
Each time, the app said "this may have write errors, fix them [yes] [no] [cancel]"

Can anyone say what might be up here or should I ignore this message?


Note - I am trying to get my collection of apps ready, my DreamCast is on order and not here yet.




Thanks.
