I've just bought a new Dual DVB-S tuner to add to my HTPC but I've exhausted all I know in trying to get the some of the channels working.  Here's the rub:

The tuner card is: TBS6991SE DVB-S2 Dual Tuner Dual CI PCIe Card

It scans and finds all channels no problem but it freezes when trying to play back anything on 12707 where the provider is SkyNz and 12456 where the provider is MediaWorks. Yes, it will play Kordia provider channels on 12456 like Cue, Shine, Choice.

 

In the same PC I have an old Hauppauge DVB-S card which scans and finds all channels and will play back everything including Prime, TV3, Four or TV3+1.

I also have mySky and it has no problem playing everything.

I use a 4 way splitter but have isolated that by plugging straight into one of the tuner ports, still no luck.  I've tried various LOF settings but still no luck.

I've ensured the driver is the latest 1.0.0.9 and even tried an older 1.0.0.6, no joy.

I'm using LOF1 Low 10750 and LOF2 high 11300 with the LNBswitch set to zero.  I'm testing using MediaPortals TV server configuration (as I couldn't get anything to scan using the TBS out of the box software).

Any idea's would be awesome.

Cheers.
