AFAIK you can use an s-card in a Premiere/Premiere XL, however, you're limited to one tuner (unless you also have an OTA feed).
...........IMPORTANT: Premiere and Premiere XL are NOT compatible with single-stream CableCARDs (S-Cards) or cable boxes.........
aaronwt found the correct answer. TiVo used to have this posted in the technical faq...Voila! Conflicting answers!
I'm not the originator, but I have a 'dead' S3. Plugging it in powers on the fan and the drive gets power (I can feel it has power/is spinning).. But the front lights never come on, and no video is output.Just out of curiosity: how did your S3 just "die" to the point you had to purchase a whole new unit? What are you doing with the old unit?
