Converting a 1 scart digibox to 2 scarts ?
 
Dirt cheap but 1 scart only but an almost punch-out in the case for a second
scart for other models. To use on TV and a recorder. Easy to get in the case
and cut out hole and mount a second scart. Can you just straight parallel
jumper across the video and sound and ground lines (signal drop/ impedance
problems?) and do you have to put a DC block in for aspect ratio control
conflict?

The audio should be ok but the vision will be double terminated. The
equipment fed from it *may' compensate but I wouldn't bet on it.
And given how cheap these things are it's not worth the bother.

So for a 15 GBP Asda MDS V3 of 2008 its possible to add in a second Scart
and so feed both a TV and recorder.
Jumpered lines 1,3,4, 17,19,21 and no problems on this pair of TV and
recorder.
Nice obvious on/standby LED indication on these and echoing of zapper signal
and retention of settings on power off , so can be used atached to a
reserve/second recorder, without TV, for simple recording, after initial
installation. Very much lower power consumption , one large NXP philips chip
and not much else other than memory and tuner in these.

Also showed that the problem with 2 channels on the other digibox was not an
aerial /feed problem but something internal to the unit, as the 2 channels
now come in strong.
