MV protection question for the ILO

[johnahl]

This MV stuff sure is confusing.

I have a Sony DVD player model NS-315.
I have a Philips DVD player model DVP-642.
I have an ILO DVD recorder model DVDHD04.

These first 3 tests are with an original copy protected DVD.

1. Copy using ILO only from DVD to HD - wnw(will not work). Understandable
2. Copy from sony to ILO front RCA plugs - wnw.
3. Copy from philips to ILO rear SVHS plugs. OK.

Now that I have it on the ILO's hard drive, I make a copy to DVD media. OK.

The copied media now acts almost exactly like the original. IOW, if I put the disc in the Sony and try to copy it to the ILO's HD, it reports protected just like step 2 above. But, I now can put the disc in the ILO and copy the contents to the HD, which I couldn't do with the original.

I'm really surprised that the disc produced by the ILO has copy protection??

Here is my question: If I install the hacked ILO software, will the MV protection be removed from any DVD's produced by the ILO?

First off, Macrovision is embedded in the video signal. The ILO hack just ignores it.

With that in mind, the video you copied in "real time" to the ILO resides on the HDD with the MV code still embedded. The copy process didn't remove it, just ignored it.

The hacked ILO firmware disables the MV sensing in the ILO, allowing a video with MV encoding to pass through undetected. It does not remove it.

Therefore, if you take the video on the HDD and copy it back to a DVD and tried to copy that "real time" into a non-hacked recorder, it would still fail.

The reason the copied DVD would allow you to transfer from the disc to HDD is because it is in DVD VR format, not DVD Video.

I hope this helps

Please re-read my question. I have not installed the hack to the ILO. How was I able to save the original DVD to the ILO's hard drive?

Not all DVDs are copy protected. Easy as that.

Yep, it is as easy as that when you don't read the question. The DVD is copy protected. Please read the first post in this thread. I know the post is rather lengthy but, I don't know any other way of explaining what is going on.

It is obvious that the Phillips player is cleaning the signal up before sending it out of the A/V jacks. Some players have video enhancing circuits that may clean the signal just enough to not trigger the MV sensing in the recorder. Again, it's not removing it, just disguising it. This is why, when copying the recorded clip to a disc and replaying the copy, it will shown up as protected, the MV is still there.

The best test would be to try another protected DVD in the Phillips player and see if it also copied or if it fails. If it fails, then the DVD you first used has a weaker MV signal embedded as was able to pass. If it works, then the Phillips player has enhancement circuitry that's cleaning it up.

If you install the hacked version of the firmware, it won't matter which player you use to play the original disc. The ILO will just ignore the MV.

In short, you have nothing to loose by installing the hacked version.

Well, your question is a bit mush-mouthed, and all the important details are missing. Like the original disc info, etc. Your belief that the disc is "protected" because a Sony player says so is unfounded. Furthermore, the HDD on a DVD recorder does not allow for "disc backups" ... that's not why it is there.

Thanks very much. It makes more sense the way you explain it. I think I will install the hack just to make sure.

Thanks again for all or your help.

What is it there for then? Only to record from TV tuner? Why is it ok to record from VHS to HDD and not from DVD to HDD ? What if I wanted to play the DVD in the DVD recorder and start recording at some point just to record a little snip of the NON copy protected disc playing ?

why not?

Yes, to record from input to HDD.
The other stuff you ask ... no.

If you want to do all that, buy a computer.
