Hi Andyj00
The behaviour you are describing is a hard drive issue. Your tivo box will need replacing. Looking at your previous posts you have broadband with VM so the tivo will be swapped out for a V6 box.
It depends how quickly you want this fixing. You can wait a day or two and a member of the Forum Team should pick this up for you and arrange a tech visit.
Or call 150 from a Virgin landline, or 0345 454 1111, option 2 (Faults)
When calling Faults ignore all the options and don't press any buttons then you should be placed into a queue and an agent should pick up the phone and book the tech for you.
