I seem to have the same problem as many people. Red flashing light. Solid blue light, nothing happens on screen, it just says starting up.
It looks like the fix is only ever sent privately (weird). So could someone send it to me please.
Do you have a TiVo box or a V6?
I suspect the secret fix you refer to is either be a reset using a particular combination of buttons, or reporting the fault to Virgin who may replace the box.
A quick search turned up this thread which may be helpful...
