Hi Andy
OK i updated back to build 753 so got the ghosting on multi setting, installed the pluging.pyo and videohardware files and restarted enigma. on multi all seems fine now however i did try 50 & 60mhz, 60mhz still gives ghosting and strange when i tryed 50mhz bbc1 hd was ok but when i changed to bbc1 wales sd the ghosting appears but then when on another bbc1 region in sd it didnt signal level on all channels is 99% so can discount signal loss. 50mhz on some some other channels also gave the ghost did note when zapping you get a microsecond blank screen as if its switching mode .
By the way i didnt load the folder in the zip file _macosx...should i as it dont appear in the file you wanted to post these new files to, also for others who maybe trying to test are they for both solo and duo versions of vix.
if i note any other problems overnight i will report back here
