Bash malfunction, or something else ??

Reference materials on commands and features of BASH that I have consulted include material stating that a line command in the form

$ command [options] [directory (if different than the current directory) ] > [filename]

will re-direct the output of the command from stdout to the named file.

In evaluating the installation of FC2 on my PC (box?), I have noticed a difference between outputs sent to stdout and outputs to > [filenames].

Is this a bug?

To illustrate, cdrecord -scanbus > scanbus.txt on my machine produces the following text file.

There are six more lines of output sent to the display screen than are sent to a file via use of the > [filename] option in BASH.
