I have been successfully recording vhs videos on to my computer. However I have an intermittent problem. Every so often the sound records but the video, when played back to edit, reverts to the first video I recorded. The correct images appear on the screen whilst transferring but on playback to edit I have the wrong images but the correct sound. I have reloaded everything, closed the programme and the computer and started again, removed everything from the program as far as I can see and it is still happening. On this occasion I have tried 7 times and it still shows the first video not the current one. Help would be appreciated! Thank you
