How exactly do you want to connect them gary?

1) aerial --> VCR --> amp --> TVs
- remote TVs cannot see STB output

2) aerial --> VCR and separately STB --> amp --> TVs
- remote TVs cannot see terrestrial channels, main TV cannot view terrestial channels while VCR recording cable channel

3) aerial --> STB --> amp --> TVs
- VCR cannot record terrestrial channel while main TV is watching a cable channel, remote TVs cannot see the VCR.

4) aerial --> STB and separately VCR --> amp --> TVs
- very little would work!

So long as the signal is above a minimum threshold the picture quality will be defined mainly by the SNR at the receiver. Yes, this will deteriorate slightly each time it goes through a box but the effect should be minimal. The best way to improve this is to fit a better aerial. Okay, I will admit you would be slightly better off if you ran the aerial through the VCR first and then through the STB but then I couldn't get the analogue bypass option into the same diagram!
