You can't.

The V+ is not designed to work in the way you describe.

All the splitter is doing is feeding both analogue and digital signals into whatever input you plug it in. Feeding DVB-C signals into the aerial in on the V+ is why you are getting the problems with the digital signal.

Virgin used to do an analogue bypass which would strip out the digital signal before it was fed into the aerial in. This was stopped in January 2007. This was because from this year, Virgin will be switching off the analogue signal in those areas that can get Digital.

So even if you had the bypass, when it is switched to digital only, there will be no analogue channels on the cable, and the only equipment that can pick up anything is a Virgin STB

This has already happened in Coventry.

The only way to do what you want to do is to use an outside aerial. Obviously, you would then either need Freeview boxes come Digital Terrestrial Switch off in your area or additional cable STBs
