In Carbonite you are not able to "Fly a Key". The DVE is doing a PIP only.
However if you are making the logo in an outside image editor (i.e. photoshop) then you can make the image the size you would like it to be and then position it using the X-Y attributes of the Media Store channel.
For Logo's and Bugs we recommend that you make it the size you want it but not "raster Positioned" that way you use less space in the Ram Cache and are able to just use the Media Store to do the "dve like" positioning.
