[SPEEDWAY]

Having the same problem in the Edinburgh area, its effecting the V+hd box but to varying degrees depending on channel.
Its been like it since the network went down one morning last week for a few hours.
I wondered if it may have been effected by my adding a 5M extension to move the box to the next room.But that had worked fine for a week before the area outage.

There has also been very slight pixilation on a couple of channels on the Tivo.
