How determine DVB-S2 card?

[Ali H.M. Hoseini]

Hi all,

I'm using getstream for more than 3 years, and it's a very stable,
light and fast program.

Now I change my card to Tevii S464 S2 card, but when I use dvb-s2 {
tag in my config file, getstream says the card is dvb-s and this
option is not supported.
I'm sure the card is S2, and I easily scan S2 frequencies with scan-s2.

How getstream determines a card is S or S2? and how could change this behavior.

Best regards.
