Remarks enclosed CyberLink Media Suite - choice of internal or external burner.

On my external burner could not be accessed for burning with Power2Go (select Settings Information burner, does not change the preselected burner). If you choose for example from the Utilities Suite, then "Disc image burn", so you can select the desired burners here. This "Burn disc image" to close again and then returns to Power2Go. Now you can burn the selected burner. This Macke also older Power2Go versions.
Apart from this problem solved the Buffalo worked without any problems.
