Does anybody know if you can split a Composite Out signal (say output of a DVD player) to two different destinations at the same time.

I know DSE and Jaycar sell video switches, but their operation suggests you can only send the signal to one place at a time.

Thanks

Yes you can, the preblem you have is the quality after the split.

What exactly are you wanting to do?

If you are wanting to split to two TV's, you could run the AV cables to one TV, and then run another set out of the AV out on that TV, which will mean you do not need to split.

Otherwise you can use, a 1xRCA plug to 2xRCA socket adapters.

I was wanting to run one direct to Composite In on TV and the other to an RF modulator to distribute around the rest of the house on RF coax.

Have just had a thought though. Perhaps I could get a modulator that has Composite or Scart pass through, so I could go DVD Player < RF Modulator < TV.

Yes you can split composite. I recently installed a 4 way composite distribution amp and then used a couple of cat 5 balun's to distribut Sky to a projector. with fantastic results. You can also get componant amps and SVHS. Have a look at somethin like this.

You cant use the Y adaptors because that will make the dvd player see half the impedance. If you get a modulator with switchable termination you could use a y adaptor sucessfully, but the termination of the TV is likly to change when turned on/off which will mess it up.

If your player has svideo and composite outs, then you could use svideo locally and composite for the modulator, or if the local tv is old and has no svideo then get a cable to combine that output down to composite.

Otherwise you are looking at getting a distribution amplifier.
