I have AC3 filter v 1.50a installed. The AC3 filter is installed in C:\Program Files\AC3Filter, the file is ac3filter.ax

Every time I open Super (v 32), it deregisters ac3filter.ax and reigsters as AC3 file its own, v 1.09. (C:\WINDOWS\system32\ac3DX.ax).

I then have to reregister ACF3 filter 1.50 using regsvr32

I haven't checked whether any other codecs are similarly deregistered

That is a nuisance. Any way of having it leave my own codecs alone, even if it vthen also registers its own?
