From the instructions of the pioneer DVD recorder book:

Quote:
"please note: All DVDs produced from this machine are Copy Protected."

Slysoft, Please fix this problem

i imagine slysoft would need the IFOs in order to fix the problem.

isntead of posting on a board where James may stumble across it and then have to ask you to email him the appropriate files, why don't you follow the instructions in this post and explain the issue so they can get to work on it. I'd guess this is something they'd be interested in as I'm sure if one company is doing this with their discs, more will follow.

According to AnyDVD, there is no protection on the disc, so it should copy. Maybe this is another problem.

I sent the .IFOs to slysoft, hopefully they will comeup with a solution.

Looks like you're trying to make a copy of a bad copy...since the media is a DVD-R.

because his user's manual for the recorder states that all discs produced by the machine are copy protected, it's possible that it's a copy protection that anydvd hasn't been designed to pick up just because the issue hasn't been encountered. Correct me if I'm wrong, but I don't think Anydvd can recognise somethin git's not programmed to recognize.

i can't imagine the protection itself is anything too intense...I mean the studios didn't even get ripguard to work for more than a day or two before it was cracked.

it could even been some kind of proprietary protection from pioneer, who knows.

or it could be absolutely nothing! let's wait and see what slysoft has to say about it.
