TataSky is Videoguard, and need to set at OSCAM:
Boxid:11223344 (your own BOXID) (4 Bytes)
ins7E;1122334455667788990011223344556677889900112233445566 (26 bytes) (your key dependend from card)
k1 unique pairing key: 00112233445566778899AABBCCDDEEFF (your key dependend from card) (16 bytes)
If you have set Boxid and ins7E you should get a ECW at the before non wotking Channels, if you get it, the boxid and ins7E are right!
CAID 0944 have some 3DES Channels. I can only help at DES (Brutforcing).
For 3DES k1 Key you need CA-Serial and EMM's for your Card.
Better choice is to use 09AA TataSky Card, at this i can give you your k1...
With newest OSCAM it work both Cards.
