As title says, this was on the first TiVo box and an engineer said it was corrupt hardware/software and swapped the box out.
It used to be only if switching to ITV1 from any channel this happened but last week or so it is on pretty much every channel. I have to pause the channel then press stop and it makes the picture appear OK. Does anyone else have this issue, or is it a case of calling Virgin and getting an engineer out to look at the box again?
I'm really sorry to learn about the problems with your TiVo box.
I've been able to locate your account and run some tests on the set top box for you, we're not detecting any issues with the set top box at the moment although I've requested a member of the team take a closer look, as soon as I hear back from them I'll be in touch.
I had this very similar problem for months and was told nothing was wrong from VM side of things. Was occurring often and then suddenly stopped for a while. Only remember it happening the odd time lately.
I either had to wait about 10-20 seconds for picture to show up or press the back button twice. Can't say for certain if it only occurred when I used the back button but that was what caused it majority of times for me.
Hopefully you get an update on this, I'll need keep an eye out on mine again.
