Best Intensity Pro Driver

What is the safest driver to use with an Intensity Pro. W7/Edius 7 & 8 Currently using 9.9.6. Concerned that YUV levels were incorrect on a Betacam SP Component capture, (first one in 3 years) I did try to install 10.9.10 yesterday but installation stopped halfway through refusing to load driver.

Is it only Intensity 4K where there are issues with analogue YUV levels?

Overwhelmed with a lack of response. Ding dong BM.
