Recently I have had a lot of recordings on Sky+ that playback with distorted sound and occasional breaking up (in to blocks) of parts of the pictures. ALl connections are seated correctly but it seems to be getting more frequent. Strangely BBC1 never has a problem but most other channels do. I've had Sky+ for some time now but I recently bought a DVD HDD recorder (Sony 910) and decided to try and record one of the problematic programmes to the HDD but it too had sound problems and breaking up pictures. Can anyone shed any light on why this should be happening? I've even completely reset the Sky box but it's still happening.
