VHS capture from Macrovision protected tapes DOES depend on the software.
Macrovision detection is a known "feature" in InterVideo WinDVD Creator. Anyone can verify this by testing video capture with an alternative capture application.
For example, the NorthQ NQ-6600 video converter comes bundled with two alternative capture applications. They are relatively simple front-ends using the Windows AviCap API. The FAQ in NorthQ User's Guide says:
"
NQ6600 only supports Macrovision movies, while WinDVD unfortunately rejects most others. If this happens, please use the program bundled to the converter. This is called WisAVIVapture, which will be placed on the desktop after installation.
Some users have also experienced problems with old homevideo, but no problems with later videos, seems like InterVideo thinks the aging on the film looks like copyprotection.
"
Based on the experience of capturing some 200+ VHS-tapes, I can verify the above mentioned. If the tape has Macrovision, use other software than WinDVD Creator. Suitable applications are widely available. Alternatively, if you know some programming and AviCap API, you can write your own capture application with a few lines of code.
In principal it would be interesting to know whether WinDVD Creator detects Macrovision from an information send by the capture device (i.e., "Macrovision bit set high", or if it analyzes the video stream by some algorithm (i.e., detects Macrovision from the digitalized video signal data). I suspect the later. One might be tempted to write a patch for WinDVD Creator to disable the Macrovision "feature". To my knowledge, there is no registry/setting hack for this. Anyone knows better?
