You can't backup DVD's through the actual DVD player. You'd need a computer to do it. You can use Handbrake to rip it, and then Toast to burn it.
handbrake isn't for ripping, it's for encoding. to rip you want a program like mac the ripper or ripit.
If you have toast its real easy. Just use the copy option. You can also drag and drop the videots folder on the DVD onto your computer which copies the dvd to hard drive and then use toasts Video DVD via videots folder option. If you don't have toast, a free program called Burn can also copy the DVD. MacTheRipper is only for copy protected DVDs and Handbrake is to encode it for playback on an ipod, appleTV, Xbox360 ect.
I'm guessing this wont work as its not a DVD recorder, its just a reader, or the OP wouldn't have asked his (incredibly cryptic) question "copy do I copy dvd I make". If it IS a DVD recorder that lets you copy from VHS to DVD, then the "bleedin' obvious" suggestion is, copy it twice !
If you haven't got a DVD recorder. Your gonna need to get one. Then copy the video to DVD. Then the computer can become involved. If you want you can cut the middle man, and digitize the VHS to the computer using final cut, or iMovie. You will need a digibox to get the video signal into your computer though
Original Poster (aka YOU). Anyway, you're asking how to use a DVD-VHS standalone player to make DVD's of VHS tapes, and then make a DVD copy of that VHS-Copies DVD. You gotta be a lot more clear (unless English isn't your first language). Anyway, you'll have to figure out how to copy VHS to DVD cause that doesn't involve the Mac at all. To make a copy of a DVD you'll use a program like Toast to make a copy.
He's got to be clearer even if English isn't his first language. Bob, can you create a DVD from a VHS tape using your Sony? (Forget the Mac for now). If the answer is 'yes', do it twice, now you have a copy ! Or, experiment with 'Burn' (free) or buy 'Toast', to copy on the Mac. If the answer is 'no', you will have to spend money either on a new DVD/VHS combo that will let you copy directly within the equipment or on hardware to let you connect the Sony to the Mac.
If the tape is copy protected, you won't easily be able to copy it to DVD. I am still not clear exactly what you are trying to do. It would help if you would use full sentences and explain what your problem.
Jeez, is this thread attracting all non-English speakers with mundane questions? They do have Mac support in other languages don't they? Anyway, to answer the question. You just need a DVD burner. Hard drive and RAM really don't apply (unless your computer is 5+ years old).
Play nicely, now. To the others: it helps if you write longer posts. That way we have a better chance of figuring out what you're talking about.
When the DVD is made the Sony makes it copy protected. Is there something I'm doing wrong in the process of copying the tape. Is there a hack to remove copy protection on the VHS? Using the sony!!!
At last you found the ability to wrote in entire sentences so we can understand ! So, seems to me there are two things you could do. First, since the Sony does seem to be copying to DVD, do it twice, then you'll have two DVDs. Second, if the VHS tapes have the write protect tab punched out, put some tape over that so it appears to be there. My DVD/VHS combo wont even copy from a tape that has that tab missing. Maybe yours will but produces a copy protected DVD if the tab is not there? Which leads on to the third point, read the Sony manual. And fourth google for the Sony producing copy protected DVDs.
