Just for facts sake: (VCRs/DVRs with) RGB signals didn't "get around that pesky Macrovision protection" by default. Some (few) models perhaps did; but RGB signals
weren't inmune to MV by design, quite on the contrary.
Also, given that VHS was inherently a (modified) composite format family (it records colour-under), there was NO real advantage in RGB output over S-Video. The latter was as good as (S-)VHS got.
That said, there
were a few (S-)VHS VCRs with RGB out —
- some early ones from Philips (VR813, as already mentioned, but the picture in RGB wasn't that great),
- some pro series from Panasonic/JVC (e.g. AG-8700, component out)
- Philips and JVC even marketed (briefly) a couple of S-V → RGB transcoders (at the time, there were few TVs with a S-Video input): Philips AV5181, JVC KMV7
- and later, the Thomson DVH-8090 could output RGB too (but only recorded composite or S-Video — even from the RGB-in, even in D-VHS!).
And —as
@mhennessy &
@cmjones01 pointed out— the S-VHS models quoted by
@emeritus are RGB-passthrough only.
