RCA 6T75 Restoration (16GP4)

[dobulee]

I figured lots of you guys would have experience with this, so here goes.

Im currently using a VCR to RF modulate for the set, which works great for downconverting all the non VHF channels from analog cable.

But, if I want to watch a DVD (or downconverted HD, or streaming video players) using the VCR as vehicle to RF modulate, i'm having Macrovision Copy Protection Woes, where the macrovision pulses screw with the VCR's AGC circuitry and cause annyoing fading and loss of vertical sync.

Have you guys had luck with external RF modulators for this purpose? I assume these do not usually strip the Macrovision, but leave the TV to still deal with it.
My questions are:
1)Does the AGC in your Vintage TV typically deal with Macrovision gracefully
2)Do the macrovision vertical sync pulses show objectionably in the vertical retrace period?

If results are poor, I could buy a video stabilizer to strip the Macrovision before RF modulating -- but i'm trying to keep the 'number of wires and components' count to a minimum!

Thanks,
Alex
