Hi everyone, I think I might be encountering the same issue.
SVP worked just fine on my computer up until a few days ago where it would continually crash, so I uninstalled SVP and MPC-HC and reinstalled everything using the download provided on the main SVP page.
Now I'm getting this error, and I was wondering where it is I need to check to see if I'm running LAV in software mode.
My specs are:
AMD Athlon II X4 3.0GHz
AMD Radeon HD 6850 1 GB
4GB DDR3 RAM
