Watch and record TV on computer

We recently got a new Satellite TV service. The receiver has DVB-S2 logo and smart card slot with the card inside. I’ve found specifications for the box here: http://www.servsat.com/_pdfs/Coship%20cdvb6252.pdf.
In my understanding TBS6928, TBS5980 or TBS6991 should help me watch the channels on my computer. Am I right? Also is it possible to watch one channel and record another at the same time?
