I have enjoyed the TIVO with no problems for a little over 2 years. The TIVO was working fine when I went out of town for Christmas. When I returned, I saw a very snowy picture on the TV screen. I removed the TIVO from the network and plugged the cable straight into the TV and the picture was fine. The shows that were recorded on the TIVO prior to Christmas will play fine, but all subsequent shows are very snowy. I have checked the cables, and everything seems to be OK. Has some component gone bad inside the DVR? What has caused the sudden appearance of snow on the TV? Any help is appreciated.
