I bought Samsung DVD-VR355 which DVD-VCR combo recorder from Future shop In December 2007 and I have not used the VCR section until recently. I have lots of VCR tapes that I want to convert to DVD using this machine and have started doing so. However I have a problem both in video and audio while recording from VCR to DVD. I can hear the sound of the video but it is distorted in that, it makes hissing or rattling sound when VCR tape is playing. Some the video also seems to be shaking sometimes and flickering. I tried to clean VCR head-I mean I have cleaned the VCR head without any success and continue to have the same problem. Anyone knows how to fix this or anyone knows what causes this kind of problems. Please help. I use Sony DVD-R media and the VCR tape is Memorex SHQ T-120.
