Download the DVCPRO 50 codec from Matrox. I know the link is posted on the site here somewhere -- do a search -- or just Google "DVCPRO 50 codec Matrox download."
David, is there a way to manually install the codec? It seems the registry editor included in the codec .exe is causing the problem when I install the Matrox product.
I had the same problem trying to load the driver into my xp64 os, what I did was unzip the file on my xp32bit machine and then i took the unzipped files across and loaded it.
right click on the exe unzip to...then load the _instpgm.exe file, that should do it.
I then just right clicked on the .dll files and clicked register DLL, not sure if you have to do that but i did and it works.
