I’ve run into DVD decoder issues a few times lately at work, this is a handy tip, from WXPNews:
How to find out what DVD decoders are installed in XP
Have a DVD that won’t play and suspect you don’t have the correct decoder installed? You can find out what DVD decoders are installed in Windows XP by doing the following:
- Click Start | Run
- Type cmd to open a command prompt window
- Type dvdupgrd /detect
A dialog box will show you the decoder name, file name, version and company that makes it. Note that this doesn’t work in Vista.
