My Roxio VHS to DVD for Mac all of a sudden shut down last night, after using it for only 2 weeks successfully. It's the same problem as stated here. It tells me to connect the device to any USB 2.0 port, which I have done in all imaginable ways possible. Why did it quit when I made no updates or changes to my computer? The USB ports work with every other device I have, just not the Roxio device. Roxio has not returned a message to my technical support complaint. For the price, it should last longer than 2 weeks. Any suggestions?
