Hi toto163,
there have been a few posts concerning Titanium 2 cards, which seem to be better known as Titan cards. If you register and visit:
_http://www.titancard2.mine.nu/forum/index.php
you will see at the moment they seem to have good support, for both Con*x & Sec* 2, but who can say how long this will last.
Buying a card seems to be pure luck, I've had excellent use out of my old Titanium and MII cards, but who can tell how long any cards will be of use. It seems a matter of do your research and then take your pick, and hopefully it will give you good service. If you buy a card for around £35 and have 6 months access to all channels you have a bargain. New cards seem to be out all the time Knot, Knot 2, Opus etc....... So it's a matter of pot luck, but always visit the web site first, and find out which Cams/receivers these cards are compatible with.
Best wishes
Mickha
