Is that like the CI interface on a full featured TT card? I _think_ those have a CiMAX chip on 'em. If it is there are docs on it here. http://www.atmel.com/dyn/products/product_card.asp?part_id=2356 (The Atmel T90FJR seems to be derived from the CiMAX) -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
