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...  Przechwytywanie2.jpg 



I know this card is really old but it still enough for me. Someone know how to fix it?
