Can you split the Virmin Media cable in your home and then have multiple boxes independent of each other?

Hang on, its not that simple sorry.
Yes you can buy a splitter and have multiple boxes in your house BUT the boxes work within a set range of signal (db) so if your first box is getting the a perfect signal when you add the spilter you will reduces its signal and so your first and second box will be on reduced signal plus you have to take into account the signal loss over the cable too so if your running loads of boxes then they may not work.
For your downstream you want the signal to be between -15 dB and 15 dB as a minimum. Ideally, you want to be between -8 dB and 8dB per box and then you have your upstream to consider too, You want this signal to be no more than 55 dB. The lower this signal level is the better! Now when you look at a splitter it will tell you what loss you can expect per port just from the spliter, with the cable depending on what you use, Losses over 100mtrs For RG6 1.9dBmV @ 5Mhz, 6.9dBmV @ 100Mhz and 18.5dBmV @ 750Mhz and For RG11 1.25dBmV @ 5Mhz, 4.25dBmV @ 100Mhz and 11.9dBmV @ 750Mhz
Ohh and you'll need to cap the open ports on any spliter to prevert signal loss and interferance. Sorry but been an ex VM service engineer I've gone to many a house where someone has done their "own" cabling and then the boxes no long work.
