The flicker suggests to me that the video is behaving similar to Macrovision encoding. With Macrovision-encoded VHS the picture looks fine on a TV but is distorted when copied. The Roxio device doesn't copy when the tape has Macrovision so that isn't the issue here, but it sounds like a similar effect. What I'd do is connect a video stabilizer between the VHS deck and the Mac, but you probably don't have one of those. You might try cleaning the heads of the VHS deck or play it through another video device on the way to the Mac. This may not be where the problem lies but it's the first place I'd look. You also might try fast-forwarding the tape to the end and then rewinding it to the start before beginning the playback for recording. That was a recommendation for playing tapes in those old days. It seems less likely to me that the encoding application is causing the flicker rather than the signal to the device being slightly unstable.
I'm just a fellow Toast-user so please don't blame Roxio for any misguidance I may provide. And do let me know if your issue gets solved. Cheers from Eugene, Oregon!
