ok, i`ve downloaded the flvsplitter, but where do i have to put the matroskasplitter.ax?
Make a folder with a name you remember & put it in there, then run a cmd window or in run command type
regsvr32 "C:\The New Folder Name\matroskasplitter.ax" (you can also drag & drop matroskasplitter.ax on run command after you have typed regsvr32)
