When trying to burn ordinary audio cd's, there are a few messages that appear, resulting in the ultimate failure of the procedure; thus one whole cd is wasted, as well as time:

Insufficient memory on device, delete tracks to make space. This appears despite the fact the disc is capable of holding no less than 702mb (easily enough to fit one album of music!).

Something about a medium write error.

and another which unfortunately I am unable to accurately recall, however went along the lines of:

...device not responding correctly. This message appears immediately upon initiating the burning procedure, somewhat like the first, whereas the second message appears at the end of the burning procedure after an unusually long period of "finishing burn".

Also, is there a way of knowing the size of what you intend to write to the disc, before you actually do?

If someone could help me out that would be greatly appreciated.

Fantastic!!! Simple but very effective. Thankyou... But you might want to work on some alternative interface for it because the regular Leopard stacks do look cool, more so I'm affraid than the HierachicalDock, however it is still great.

Fantastic! Sapiens has saved me the time and hassle out of finding the preferable application. It's easy to use, and comes with a stylish transparent interface. If you use a variety of applications and want to reduce the length of the dock (which in my case was so long that I could hardly distinguish the icons) then sapiens is a great little application.
