I need something to remove macrovision/ cgms from my old vhs tapes, either The Grex
or a real TBC such as this one
with basic proc amp controls and as cheap as possible .
What do you guys think ?
Also i'd like your opinion on what that guy is talking about, i quote him:
Disabling Macrovision was simple on my Toshiba (dvd recorder). A search of chip numbers found the one that generates Macrovision, and a pinout. That chip is fully configured during boot via SPI. The SPI interface isn’t used again unless you alter certain video output options in the setup menu, or insert a DVD which tells the player to activate Macrovision. And the CPU either doesn’t check or doesn’t care whether these further operations succeed. A little 555 circuit that clamps the chip select line a couple of seconds after power up did the trick. Video settings can still be altered via setup followed by a power cycle. Was quite useful when I was using a VCR as a video source selector, as it was affected by Macrovision even for that purpose.
The way he talks about it seems like a piece of cake, but i know myself i put my hands inside an electronic device and it's good for the recycle bin. Anyway this caught my attention, seems like a workable poorman's solution..just what i like. Opinions, thoughts welcome
