I have a Windows 10 64-bit desktop with 24GB of RAM, 2GB of RAM on the video card. When importing a Hi8 tape from my Sony Hi8 Camcorder into the Dazzle DVD Recorder HD, the image on the import screen is crystal clear. But when saved at 'the best' quality setting, the video is grainy. Ideas? I have a lot of Hi8, 8, and DV tapes to burn to DVDs.
