Try to import video from Terratec Grabster AV 300 device on UBS port.
Device is properly connected the supplied Magix software is working and is able to grab video and sound.
When I try to import in Movie Studio 16 the message "the device 'AV 300 GRABSTER' could not be opend. Pleas make sure that it is turned on and not being used by another application or user" is given. Is this a wrong setting ?
