I have just currently replaced my previous single tuner DVB-S2 card (Floppy DTV) with a TBS6981 dual tuner card. My HTPC runs Windows 7 and the Windows 7 Media Center for watching and recording TV. All in all, the 6981 works like a charm, no tuner losses, no standby problems etc. However, there is onle little problem: The two tuners are connected to a Technisat Multytenne Twin multi position dish with diseqc control. I use this setup to watch German TV on Astra 19.2° and British BBC and ITV on Astra 2D/28.2°.
Since I switched to the TBS6981, I no longer receive BBC-HD, BBC One an BBC-HD. All other BBC and ITV stations (including ITV-HD) work flawlessly, yet the first mentioned stations just do not appear in the channel list, even after a full satellite scan over all transponders. A dedicated transponder scan on 10847Mhz vertical (where BBC-HD sits) does not find the station either. There used to be no problem receiving all these stations with the previous setup, so I guess the issue must somehow be connected to the new tuner card.
Hence my question: Is this a common problem (albeit searching the forum did not reveal any similar issues) or has someone else experienced a similar problem before and knows how to solve it? Would be great if there was a solution...
Many thanks in advance,
Andreas
