It should work with MythTV, do you have experience set up DVB-S/S2 with MythTV?
Maybe you can contact us via chat and set up remote access so we can go through the mythtv setup process together.
Yes, I have been running mthtv for over 15 years! I have just retired my earlier server for a new one, this only has a single PCIe, which I have my DVB-T card (Which works fine) From my original post you can see that I have installed the driver, and it can be seen by the OS and Mythtv. However, I have not been able to get it to tune. See my original post.
