Mack13: So, can I record to Tivo from my old SD sky STB? - cant see any A/V type inputs.
This is what the Series 1 TiVo is used for, but that is standard definition only. I use mine only for analog reception, but my sister has one paired with a Sky Pace box.
As already responded the S3 (TiVoHD) has no AV inputs, although interestingly the motherboard and case have space for them.
