The video injection schematic looks good.

If you have a DTV box I'd try that to confirm. The DVD recorder/VCR and computer methods I have to create DVDs give the option to make a disc with the macrovision flag set (though they just call it copy protection or something like that). That could be set default to on in your system or you could have a DVD player that constantly outputs it. DVDs don't come encoded with macrovision and only have a flag bit that tells the DVD player to create and mix in the macrovision signal. There are some DVD players where one can easily set the machine to always neglect adding macrovision and the other way around is not impossible either.
