The thing is there is no reason a V6 box should be stuck on the waking screen for any prolonged period of time, other than it having a bit of a moment. Which 99.99999% of the time can only be fixed by removing the power.
I have just seen exactly the same problem tonight. This box looks like it skipped the testing phase. I'm disappointed to see there's no response from anyone from Virgin on this. I "reset" (power-cycled) the box and (after 5 minutes) normal service was restored. However, it leaves one wondering about the reliability of the box... I'm tempted to disable auto-standby/sleep. My rationale is that if it (the box) gets itself into a state where it cannot come out of standby then:
a) Will it actually record the preset programmes I want it to?
b) What if it finds itself spinning in this endless loop when I'm trying to turn it on when I want to watch something? (I mean it fails to turn on 5 minutes before the Queen's speech for example)
I solved my problem by leaving the V6 in always on (suggestions off) and then leaving it in standby overnight BUT also turning my tv off (rather than leave that in standby). It seemed to me it was something with the tv that was causing the problem in the first place.
Since doing this I've not had the problem back. Let's hope the fix comes from VM soon.
