The S3 manual says there's a limited warranty with 90 days of free labor and one year parts exchange. Within 90 days you may be responsible for shipping, beyond 90 days you may be responsible for shipping and labor. (I've added the word 'may' because I expect TiVo to take care of their high-end customers.) More important, the S3 remote operates the S2. I like to take the glowing remote with me.
