Hi,
Without going into any detail, in Versions 5.0.1 and less you can use 
Experimental`BinaryImport.
So load the Experimental package:

<<Experimental`

and then use BinaryImport. You obviously know the header structure and 
so you can select how bytes are read in at a time and where from.

In V5.1 this has changed and you can use BinaryRead to read in specific 
chunks.

Cheers
Yas
