Use "professional' VHS/DVD video equipment, TBC, or video enhancer/processor/stabilizer Use "professional' VHS/DVD video equipment,TBC (Time Base Corrector), or video enhancer/processor/stabilizer. "Your" VHS tapes do not contain "codes" preventing them from being copied to DVD. On the other hand,"Their" VHS tapes usually have Macrovision copy protection which prevents licensed material from being successfully copied except on "Professional" video equipment or computer peripherals.

You can experiment with different equipment,not all VHS or DVD recording equipment handles Macrovision the same way. Other than "Professional" VHS or DVD equipment,a professional TBC (Time Base Corrector) correctly repairs the video signal. http://www.amazon.com/s/ref=nb_ss_gw/104-4325501-0970334?url=search-alias%3Daps&field-keywords=time+base+correctorSometimes a "video enhancer", "video processor", or "video stabilizer"can clean up the video signal sufficiently:http://www.amazon.com/s/ref=nb_ss_gw/104-4325501-0970334?url=search-alias%3Daps&field-keywords=video+enhancerhttp://www.amazon.com/s/ref=nb_ss_gw/104-4325501-0970334?url=search-alias%3Daps&field-keywords=video+processorhttp://www.amazon.com/s/ref=nb_ss_gw/104-4325501-0970334?url=search-alias%3Daps&field-keywords=video+stabilizerAnalog Copy Prevention----------------------------A DVD recorder receiving a data stream encoded with Macrovision's legacy ACP copy prevention signal will simply display a message saying the source is "copy-protected", and will pause the recording.

This is achieved through a signal implanted within the offscreen range (vertical blanking interval) of the video signal—either physically recorded directly on the tape (as with VHS) or created on playback by a chip in the player (as with DVDs) or the digital cable/satellite box (as with all HDTV programs being down-converted to standard definition). NTSC and other video formats store the video signal as “lines. ” A portion of these lines are used for constructing the visible image by transposing them on the screen, but there are approximately 20 to 40 lines outside the visible range that are used for different things in different countries, like closed captioning.

Macrovision inserts pulses into this non-displayed area. These signals cause the automatic gain control on the recording VCR to compensate for the varying strength. This makes the recorded picture wildly change brightness, rendering it unwatchable.

On most televisions, the viewer on the screen sees no effect in ordinary playback of the modified video because the signal is outside the visible area, but some TVs do not properly blank the vertical retrace and leave dotted white lines near the top of the picture. Some newer TVs also mistake the Macrovision pulses for synchronization pulses. Another modification also used in Macrovision is the addition of colorstripes—rapidly modulated colorburst signals.

The original Macrovision technology was considered a nuisance to some specialist users because it could interfere with other electronic equipment. For example, if one were to run their video signal through a VCR before the television, some VCRs will output a ruined signal regardless of whether it is recording. This also occurs in some TV-VCR combo sets.

Apart from this, many DVD recorders mistake the mechanical instability of worn videotapes for Macrovision signals, and so refuse to make what would be perfectly legal DVD dubs of people's home old movies and the like. This widespread problem provides a legitimate basis for the sale of devices that defeat Macrovision. The signal has also been known to confuse home theater line doublers (devices for improving the quality of video for large projection TVs) and some high-end television comb filters.In addition, Macrovision confuses many upconverters (devices that convert a video signal to a higher resolution), causing them to shut down and refuse to play Macrovision content.

Some DVD players give the user the option of disabling the Macrovision technology. This is possible since the signal is not stored on the DVD itself; instead commercial DVDs contain an instruction to the player to create such a signal during playback. Some DVD players can be configured to ignore such instructions.

There are also devices called stabilizers, video stabilizers or enhancers available that filter out the Macrovision spikes and thereby defeat the system. The principle of their function lies in detecting the vertical synchronization signal, and forcing the lines occurring during the vertical blanking interval to black level, removing the AGC-confusing pulses. They can be easily built by hobbyists, as nothing more than a cheap microcontroller together with an analog multiplexer and a little other circuitry is needed.

Individuals less experienced with such things can purchase video stabilizers off the Internet. The best device for defeating Macrovision is a Time Base Corrector (TBC), although they are more expensive than the simpler video stabilizers. Discs made with DVD copying programs such as DVD Shrink automatically disable any Macrovision copy prevention.

USB-based video interfaces designed to allow DVD recording on PCs are legally required to detect the presence of Macrovision signals on any analog signals input to them, and if so, inhibit the recording, but few, if any, do so. The MPAA maintains it has every right to limit copying of movies, comparing DVDs to pay-per-view where the consumer is allowed to view the movie in question but nothing more. Many are concerned that the organization is attempting to quash fair use by disallowing consumers to make personal copies.

On the other hand the ease with which Macrovision and other copy-prevention measures can be defeated has prompted a steadily growing number of DVD releases that do not have copy prevention of any kind, CSS or Macrovision. United States fair use law, as interpreted in the decision over Betamax (Sony Corp.V. Universal City Studios), dictates that consumers are fully within their legal rights to copy videos they own.

However, the legality has changed somewhat with the controversial Digital Millennium Copyright Act. After April 26, 2002, no VCR may be manufactured or imported without Automatic Gain Control circuitry (which renders VCRs vulnerable to Macrovision). This is contained in title 17, section 1201(k) of the Digital Millennium Copyright Act.

However, there are a number of mostly older VCR models on the market that are not affected by Macrovision. On October 26, 2001, the sale, purchase, or manufacture of any device that has no commercial purpose other than disabling Macrovision copy prevention was made illegal under section 1201(a) of the same controversial URL4 June 2005, Macrovision sent a cease and desist letter to "Lightning UK! ", the maker of DVD Decrypter, a program that allows users to backup their DVDs by bypassing CSS and Macrovision.

They later acquired the rights to this software and withdrew it from circulation on the URL5 June of 2005, Macrovision sued Sima Products under section 1201 of the DMCA, claiming that Sima's video processors provided a way to circumvent Macrovision's analog content protection (ACP). As of June 2006, Macrovision received an injunction barring the sale of this device, while the court proceedings continue. http://en.wikipedia.org/wiki/MacrovisionFor more information or assistance,contact me LeheckaG on AskVille.

Where can I get a copy of the original VHS tapes for This Old House.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
