Composite is probably going to be fine. I would suggest using manual tracking to get the best possible image from your VHS tape, rather than letting the VCR automatically track it for you. As for power calibration, the software probably can't figure out how much power your burner needs to use to burn the DVD. This can be a lot of different things. Everything from cheap discs, dirty read/write eye in the drive, among other things. You might try cleaning your drive with a cleaning disc, then make sure any software related to the burning process is up to date. You can also try changing the brand of discs you use, or you might try burning at a lower speed to see if that solves your problem. I hope one of those helps you out!
