Hello Everyone here on this forum.
Before I created account here i have read many posts here as "non-registered" user. Now it's time to asks here becouse i have a hardware-software problem with my old Prof 7301 PCI card.
I have been using this card for few years without any issue on Windows 7 with 2.1.0.1 W7 x64 driver. Blindscan, ts analyze, altdvb, dvb dream, everythings works okay. Even i can lock SR=285 with this card.
but the time has come to say goodbye to old windows 7. I switch motherboard to UEFI boot (secure boot disabled) and installed Windows 10 Pro.
Since then my card its "blind" i can do only spectrum and signal analyze, but when i click stream (to vlc for example) nothing happen. All other software not working too (empty stream, no pids, no epg, scan always finish with error and nothing found)
Of course i tried two drivers:
Prof7301_Driver_2.1.0.1_W7_64
Prof7301_Driver_2.1.0.1_W8_64
i have two devices in device manager(Prof 7301 DVB-S/S2 and Prof TS capture) and both drivers seems to load ok, no errors or yellow exclamation mark.
i spend few days to try fix this error.
also tried this one with regedit but its totally break drivers and i cant even see signal, need to reload the driver.

Finally i found why my card is not working! Becouse of UEFI boot. I install the same win 10 pro with legacy boot and card started to see data again. Then installed again win 10 pro with UEFI and again no data.
I really want to use win 10 with uefi boot becouse its load faster than with legacy boot.
Tried also option called "other PCI Device ROM Priority" but its not working... 
I know this card is really old but it still enough for me. Someone know how to fix it?
