Shortage of chips ? More than that, the Twinhan DVB-S2 card, VP-1040 uses the Mantis PCI bridge, which is a new chipset as well. > >> You're working on the new TT dvb-s2 card, arent You? > > Yes. > >> Asked Technotrend? > > Haven't had any responses from TT for a while.

They did provide information that which was missing from the datasheets as well, as they wanted to go for a very good driver. The current driver, needs some more finishing touches.
