Hi, probably a stupid question but anyway: I click on the download for virtialdubmod, my winrar opened and in the zip file there are two prog or file: virtualdubmod.exe and virtualdubmod.vdi I double click on the .exe and an error messaged appeared: "this application has failed to start because corona.dll was not found. Re-installing the application may fix this problem." Even if I did extract to a different folder and the .exe is on my deskstop i click to open, it gives the same message. I tried two sites for dl they both gave me the same problem. What I'm I doing wrong or what is the prob.????????? Also I still have my old virtualdub installed on my computer, is that what is making the interference,although i thought i saw a thread specifying to use both because of the mpeg 2 codec something like that. please help a desperate woman. have several movie on mkv I would like convert to avi. thanks in advance marilor
