I have a problem with the Adrenaline drivers versions later than 22.5.1.
After installing the driver all VCE profiles in Vegas are gone. Also creating a new profile doesn't give me a VCE option.
I tried with Vegas 16, 19 and 20. But all behave the same. At least the prfiles and options are back as son I downgrade to 22.5.1, but thats not a proper solution.
