where can I find the uninstall menu you refer to? |
Start > Control Panel > Add/Remove Programs
and how do I know which codec to uninstall? |
Start by uninstalling any you can see (you can add them back selectively afterwards). Have you installed any "codec pack"?
and will the uninstalling have a knock on effect and effect other parts of the programme from not working efficiently? |
You might not be able to view videos that need the codec
