Using TiVo to Copy DVDs
I wanted to make backup copies of some of my DVD's cause my little boys (almost 2) gets his hands on them some time. I have a VCR/DVD Recorder with a extra DVD play hooked to it. However most of the DVD will not copy cause of the copyright protection. I found this weekend if I run the DVD to TiVo, have the TiVo on channel 0 I can play my DVD over TiVi. Pause it, recorded it, etc. Also I have the TiVo going to my DVD-R and now I can RECORD MY DVD's!!!! YEA AGAIN TiVO!!

it still is Macrovision compliant. This is some loophole if it is indeed a commercail DVD being copiedGrondramB said:Interesting Tivo used to be Macrovision complaint. Tivo was forced to license Macrovision to get make some features like Tivo to Go possible.
Not all DVDs are copy protected.
right but then it should have worked without the Tivo....megazone said:Not all DVDs are copy protected.
Maybe it's cause it's a older TiVo. Not sure but I did copy 2 DVDs last night that would not copy with out going over TiVo.
True, but the number of commercial DVDs that do not have any sort of copy protection are few and far between. You can easily (and legally) make backup copies of DVDs you own using AnyDVD, DVDFabDecryptor, and other programs readily available for this purpose. All you need is a PC with a DVD burner. Check out the forums at doom9.org for details.megazone said:Not all DVDs are copy protected.
I wonder what a program called dvd decrypter does? I wish you could download it at doom9.org. 
an S1 TiVo might not have macrovision because the DVD models that requires the license be added were not until S2 series.TiVo Is God said:Maybe it's cause it's a older TiVo. Not sure but I did copy 2 DVDs last night that would not copy with out going over TiVo.
PS - you can not legally make copies of protected DVDs. Fair use arguments and the fact I use those tools aside
I thought that TiVos were Macrovision compliant in the way that it recognizes that Macrovision is in the signal (passed from a DVD player or other source) and will encode the video output with Macrovision when the recording is played back.
The most you can now do with that copy is to play it back from the TiVo; you can't save to VHS. It might also not allow TiVo2Go transfers, and if so, there would be no way to make any other copies via the TiVo.
Of course, the proper thing to do would be for it to say, "hey, this has Macrovision on it, I won't record it," like DVD recorders do, but I believe the problem arises in that cable channels can possibly have Macrovision encoded on them (or at least have a cable box output a signal with it encoded), though I've never heard of that happening yet.

Whatever you do, don't combine it with another free program called DVD shrink because then you might be tempted to make backup copies of your DVDs. For example when I go storm chasing I am always tempted to burn a few DVDs onto backup DVDs this way so I can't lose or damage the originals and thus have safety for a few cents per disk.jkalnin said:I wonder what a program called dvd decrypter does?

But, of course, that would be wrong.
A Series 1 TiVo will respect Macrovision by recreating it on its output.
A Series 2 will do the same, plus limit transfers, and possibly limit recording persistence.

I use DVDshrink for my back ups. This works great as I only have a single-layer burner. DVDShrink compresses the files accordingly (and lets you toss out unneeded soundtracks, files, etc.) to fit onto a single layer disc. Works great for making copies for my daughter so originals don't need to go on the road.
You might want to check out DVDRebuilder. It's a bit more involved than DVDShrink but there is little or no loss of picture quality. DVDShrink noticeably degrades the image.
I'll assume by the smiley that you already know what it does. You should be aware that it's no longer supported and doesn't work with the latest Sony ARccOS or RipGuard protected DVDs. In any case, any discussions on this topic should really be held at doom9.org and not here. Videohelp.com and afterdawn.com are two additional sites that cover this and other DVD-related topics.I wonder what a program called dvd decrypter does? I wish you could download it at doom9.org.
How can any program get a dual layer DVD with more than 640MB of data onto a single layer disk without loss of quality?mr.unnatural said:You might want to check out DVDRebuilder.

First off, I should restate that my use has never been for making "near-perfect" copies for myself. It has only been to make backup copies of my "daughter's" movies that she would like to travel with when going to visit grandparents or for use with her portable in the car. The goal in these cases is to avoid taking the originals on the road. The originals are left at home with the Home Theater. So quality is not that big a deal.GrondramB said:How can any program get a dual layer DVD with more than 640MB of data onto a single layer disk without loss of quality?
Now, how to get a double layer disc on a single layer without highly noticable issues......easy. Two steps for me. 1, oftentimes there is very little information on the second layer, especially if it is a rather short kids movie. 2, I extract out unnecessary information. I remove things like the following:
- non-english audio tracks
- surround tracks (since it will only be watched generally on a two-channel system)
- extras
- menus (I create a movie only disc that plays immediately upon insertion)
- etc.
Usually, when I do this, the resulting movie-only track only needs 10-15% compression, if that. So, going back to my use of DVDshrink, is more than adequate.
I will check out the other program mentioned, out of curiosity.
I believe my TiVo is Series 2, it is older but has a USB port and the TiVo site says the USB wasn't added until Series 2. However I did make a copy of "This film is not yet rated" by sending to first to TiVo and having my DVD record it as it played live over Tivo. I did not TRY to save it to the TiVo harddrive. Not sure if that would work but could try.
I made a copy of that movie and two others. All three movies I have tried to copy so far, could NOT copy by just hooking DVD Player to the DVD Recorder. It give me the copyright protection error window.

I assume you mean 8.4GB for a DVD-9 (i.e., dual layer) and not 640MB. Granted, there will always some loss of quality since you're reducing the amount of data but with DVDRebuilder it's generally indiscernible. It's actually a shell application that runs numerous apps in the background to maintain the highest picture quality possible without noticeable degradation. DVDShrink is a quick and dirty app that works more quickly but doesn't do anywhere near as good a job, IMHO.GrondramB said:How can any program get a dual layer DVD with more than 640MB of data onto a single layer disk without loss of quality?
jlb - DVDShrink should work just fine for your application as I'm guessing you're not viewing the DVDs on a larger screen. Image quality is not as big of a deal on a small screen but only becomes an issue as the screen size increases.
DVDShrink can make perfect copies, in many cases. First, many discs even today are single-layered, surprisingly enough. For those that aren't, the main title (i.e., the actual movie) will often fit on a single layer. DVDShrink lets you reauthor with just the main title. (This can be a good idea anyway, to get rid of forced previews and other cruft.) And if that's not enough, you can often reduce the size of the title by discarding unwanted audio tracks (foreign langauges, commentary, DTS).
Only after doing all that would I let it requantize the disc. Usually I find that little or no extra compression is required.

I hear the problem with simply recording the dvd through your TiVo inputs is that you cannot have the title of the DVD and due to the copy protection it prohibits transfers. Now since we are on the subject of DVD decryptor I heard if you mix in a little Videora TiVo converter and follow the directions on the web site then let that baby cook for a while your gonna find now you really got a stew going!
