Advertisements I am sure this has been covered but I am not sure if this is related to the other issues I have been reading as I haven't seen these 2 issues put together. I recently purchased the new TivoHD. After 2 cards were successfully inserted I have begun to notice that the picture gets that 'digitized' issue every 10 to 20 seconds along with a brief sound hiccup along the same duration. They are not synced together and just continue to happen. Do I need new cable cars? I have Cox and have 2 SA cards installed. Would a single multi-stream card be a better solution? Sorr if this has been beat to death.
