I have the HD audio Solo and it works really good, but how come I can only get 4430 MB on a 4.7 GB disc? When I put music into another group, I get the message that I exceed the maximum disc capacity of 4430 mb. Is there something here that I am not getting? (OK, that's obivous). Can I only put 4430mb on this dvd-r disc? Thanks, for your time and info.
