You usually can't get the VCR to use the TV's Freeview tuner, just as you can't get a VCR to record using the analogue tuner in a old-fashioned TV.
You need to use the first SCART socket on your TV to connect the DVD, as this will have the required "RGB" connection, vital for the best quality pictures from DVD. (If the DVD has a HDMI output and your TV has an HDMI input, you may wish to use a HDMI cable instead).
Connect the VCR to the second TV SCART socket. If you want to record from the analogue service you will need to connect the aerial to the VCR first, and then onto the TV.
If you want to record from Freeview, you will need either another Freeview box, or you should consider buying a Freeview PVR or Freeview PVR/DVD-writer combo as this makes the whole recording a very simple process.
Mother has just bought a tv with built in free view, she has a dvd vcr combo & skybox she has had someone to connect all these up, but there only seems to be the freeviewchannels available, no sky channels, yet she can record say, BBC1 onto vcr, while watching say ITV, is it possible for her to still receive sky channels? which she dosnt really need, but she is adamant on wanting to be able to record as she can now. head scrambled with it all now, new TV has only 1 scart socket.
debs: If your buying a new LG TV (which we all rather like at the moment), then NOW TV is included as part of the smart features, as is wifi, so you can just use your subscription in the same way, but on the TV.
Other Tv's don't have it, but you can see from this list Available Devices | NOW TV - Help that there are a fair number of devices that you can use to stream from. If you buy a smart TV you should be able mirror from an android phone. If not, but a Now TV box (less than £15) and plug it into the TV.
General advice on buying a new TV (this is what I say to my customers). Find the right size (3 times the size of the screen away from it is fine - so 40in x 3 = 120 = 10ft, for example). All TV's should have Freeview HD, be Full HD, be smart and have wifi. There are exceptions, but I can't see the point of not having smart functions, etc. You ultimately paying for the quality of the panel - a 400hz screen will look better than a 100hz screen (although the 100hz LG's, such as the 650, are excellent value), and 800hz better still. They cost more, but thats how it works.
I generally wouldn't have a problem with any of the four major brands (LG, Samsung, Sony or Panasonic). Please go to a proper shop, and ask questions and look at one before buying, if you can.
2) Loop through the signal via the various boxes until it gets to the back of the TV. The Toshiba should certainly be able to take the feed from the aerial, and then have an 'out' to connect the aerial to another device. If the Digihome has the same setup, do the same again, and then put an aerial lead in the back of the TV. This is the normal way of doing things.
The disadvantages of this approach can be a) If one of the boxes does not 'pass through' the signal when the box is off, then anything further down the chain has stuck without a signal, so make sure that there is always a signal.
b) The longer the chain, the more chance there is of a weak link.
The advantage is that its easy to set up, all you need are decent aerial leads, and its relatively neat.
3) If the Digihome does not have a loop though, then perhaps combine both ways (or just do it anyway). Get a two way splitter (a decent metal one is a fiver on Amazon), and have one section going one way, and then looping through just one box to the TV, and the other branch just feeding the one box.
Frankly, whatever works for you. Your signal strength should be fine for three devices, and the second method is the 'correct' one, with no need for any extra bits. If it doesn't work, try something else. As far as the HDMI connections are concerned, use them where ever possible, because you will probably get upscaling and less likelihood of interference.
