Advertisements Thanks, I was under the impression you were between informing them you would send them back and actually sending them back. Usually people come on here looking for some help. I haven't had a problem with the 30-day satisfaction guarantee. Also if there was a problem that started within the 30 days and I opted to try and work it out with them, I've had no problems asking them to extend the return period until we could determine what the problem was. They had no issues doing that for me, including documenting explicit instructions to allow exception for full refund and free return shipping and giving case # for my records. CableCARDs are designed with standard PCMCIA (old generation laptop expansion cards) form factor, so TiVo didn't really need to design anything. The slide rails and offsets which only allow the card to be inserted in the correct direction are part of the PCMCIA standard.
