Using a DVD recorder to record radio programs

I recently purchased a DVD recorder to make copies of home movies from video tapes but have played around with it and found I could input audio signals via my receiver to the analog inputs on the dvd recorder. I've tried recording the audio only in the extended mode and it sounds very good. I used to do this with my vhs machine so I could copy entire radio programs so as to listen to them at a later time.
Any comments on doing this with the dvd recorder? Will there be a big difference in sound quality depending on the speed chosen to record the programs? The machine I have allows up to 8 hrs of recording time in extended mode. I was also wondering if I were to feed prerecorded dvd video/audio signals to the dvd recorder via my receiver would the copy guard still be a factor or will the receiver act as a filter and allow the dvd recorder to copy the movie? All in the interest of science mind you!
Comments/suggestions are welcome.
Sounds interesting? I have used a VHS tape machine to record radio concerts and am delighted with the 6 hrs without interruption. How would you compare the quality using the DVD recorder?
I too have burned audio only on DVD. Sound quality is very good. That is why you will never see a DVD recorder with digital inputs.

Forget that, if the DVD you want to copy has copy protection your receiver will not filter it out.

What you can record from a copy protected DVD is the audio only. The copy code protection is in the video carrier. Just disconnect the video from the DVD recorder.
Go with a computer program (plaenty out ther in cyberspace to copy movies) to copy that DDVD stuff. or you will orobaly get scrwed up with macrovision\.Do a test for us and tell upo i f Macrcrovision is just a "vision" thing.But on your computer it's all ones and zero's.I don't feel bad for MPAAA when someone wants to back up a CD or even rent and watch latter.But they release a new movie and within 48 hours it's being sold with covce art (never mind you a see a woman walk in front of the bootlegger who is coipying a film in a thatre).But have heard that Bill Gates has offered up "Micrsoft 10 player" instead of Macrovison which is somehow as close to needing a "key" disc before play or somehting like and if this happens I will bum out.For the price of $50 for "Lawrence Of Arabia" I feel I should be able to back it up just the way music folks don't want to dsetroy their CD's in car play.And foget inputs you can't even get the weasels who make the equipent put a 5.1 out ona DVD a 'la componnet outputs meaning you use their digital output but if you want to tweak the sound,bass managemnent etc.No wonder the software manufacturers compolain all the time they are doing with softwar what Anericans did with cars up till the 70's.Contemptible greedheads who if you wanted FM or air conditioning thought they should make more money.Then came the Japanese with two trim lines and cleaned there clocks and well all know what happened.If you expriment ad to the post.
Chazzbo, with all due respect, what the heck are you rambling about????
Sulloj,....LOL, there was a program you could buy and install in your computer. It would defeat the copy code protection and allow the user to make a perfect 5.1 copy of a (copy protected DVD). It was represented as "for back-up only" of a DVD owned by the person using the program. Through extensive lawsuites the Fed stopped the sale of the program. Infact it is even illegal to own one now. Careful Big Brother is watching......

I should of mentioned further in my post when I spoke of recording audio only from a copy protected DVD, I was thinking of a live concert DVD you might want to record the audio from. You know for back-up purposes only.

Have you discovered how to record individual tracks on DVD and select them at random like you would from a CD?

Hi Jim
Thanks for the reply. I have heard of the computer program for copying dvd's but of course I don't have it.
I was wondering if there are mod's one could do or have done to a dvd recorder to filter out the copy protection. (for scientific purposes only of course)
A friend of mine purchased a modified toshiba dvd that is "region free" which allows one to play dvd's from all around the world! So I figure there has got to be some "skunk works" type out there who has figured out a way around the copy guard. You know the old adage "If a man made it, a man can "fix" it" LOL
Yesterday I recorded 6 hours off air radio. I'm listening to it now and making a partial copy onto minidisc for my daughter. However, I haven't figured out how to make "tracks" yet. Fortunatly I can do so on the minidisc but I'll have to play around with the DVD recorder some more. I have a lot of gear so when I decided to install the dvd burner, I had to make a quite a few wiring changes which turned out to be a two day ordeal. Sometimes I feel like a "mad scientist" when I get in the back of my gear and look at all the wires.
I just bought a video switch from a guy on the Agon web. It allows the component video inputs to be extended to accept 4 inputs and feeds them into the back of the tv.
My Sony tv only has two component video inputs and I need some more considering I now have the DVD burner, a 200 disc Sony DVD changer, a Pioneer DVD player, an XBox, and a High Def cable box. I have also experimented with the DVI input on the back of the Sony TV but I find the picture is better with the component cables.
Cheers and Happy New Year!
A full frame Time Base Corrector will defeat macrovision. Look around the internet for Datavideo TBC-1000. You would install this between the outputs of the dvd player and the inputs of the dvd recorder. However, your best bet would be a simple computer program like DVD Shrink.
