Sadly, Macrovison protection works very well with video products. The only way you can circumvent it is to find a DVD recorder that will let you flash the ROM with a modified BIOS that allows you to disable Macrovision protection. More sadly, those are extremely hard to find. Macrovision is encoded into the recordings, but it's all controlled and read by your hardware. If you want to stop it, you have to change the hardware.
Somebody may have some links to sites they can post (sorry, I don't) or you could try Googling something like "crack Macrovision" or "disable Macrovision" to find sites with info or hardware models that can be modified.
