It's already been covered in another post - but roughly on average the video on Virgin's HD channels broadcast at 6MB/sec, the Virgin 4K channel averages about 24 Mb/sec and BT Sport 4K is fixed at 27.3MB/sec.
SD averages vary from anything between 1.2 Mb/sec to almost 8 Mb/sec for Sky Sports SD versions.
I'm unsure what assertions Raider999 is alluding to, but the obvious problem is that the percentage on a 1Tb disk has a huge margin of error from rounding.

My calculation gave 24.34GB for 2 hours. Multiplied by 1.75 gives 42.5GB. I accept my calculation is for video only (audio is 448kb/sec), and it isn't clear whether Virgin's software defines a megabyte as a million bytes or 1024*1024 bytes.
What Virgin haven't really tested is the lower limit of broadcast 4K as there's been no need to due to the ample capacity they have to maintain high bitrate 4K broadcasts.
