Are all Scientific Atlanta CCs M-Cards?

[pdhenry]

Skimming through the the Comcast CableCard thread it appears that Comcast uses Scientific Atlanta CableCards in my location. The TiVo.com CableCard troubleshooting page (http://www.tivo.com/setupandsupport/technicalsupport/hdandcablecards/Troubleshooting_CableCARD_Activation_and_Channel_Issues.html ) suggests that all SA cards are M-Cards. Is this the case?

They may not make them anymore, or perhaps Comcast doesn't stock them anymore, but SA did make S-cards. That is what I used to have before getting an M-card.

S-cards I believe had a blue label, whereas M-cards are teal green.

Looks like I didn't scroll far enough down the troubleshooting page. Never mind...
