We had bad thunder storms on Saturday and Sunday and our Tivo box badly pixellated on some channels. Also recordings were fouled up - jumping backwards and forwards then stopping altogether half way through the programme on More4.
The picture even rolled a few times, bringing back memories of the very old tvs which needed a thump on top.
The Tivo is mostly fine otherwise but I can't understand why it is so badly affected as to be unusable during thunder storms.
Just noticed that I have no on demand video from my Tivo. There is nothing wrong with my TV as I can watch recordings and DTV. I've just logged a report and they are sending an engineer down tomorrow. I thought this fault is more than likely external because of the weather why sending an engineer - it was working last night.
