I bought the Roxio Easy VHS to DVD Mac and it is not working at all. I've spent hours online with tech support with both Roxio and SmithMicro who sold this to me. The actual USB piece looks bent to me and is not recognized in either of my 2 Macs with USB 2.0 ports. I really want this product to convert my Hi8 tapes to DVDs. I was hoping to get a replacement USB piece, but Roxio says they'll just issue me a refund. Why won't they send me a replacement part?
