The picture just keeps glitching every few seconds. They have a 360 in another room which has no issues.
If they have a TV360 in another room, they cannot have an existing TiVo. The two are completely incompatible,
Are you referring to a V6 (that runs TiVo-software) that has been converted to a TV360? In which case it's no longer a V6, but is now just as much a TV360 as the other working box. https://www.virginmedia.com/care/tv-fault/which-tv-box
The fault sounds like you're describing picture pixellation - try swapping the two boxes around, see if the fault follows the box or remains with the internal cabling.
