I can't seem to figure this out. I've used the device manager, but it doesn't say video card specifically. Just audio, video, game controllers. Is this where my video card is located? I'm not all that computer literate so any help you can offer would be much appreciated. I'm just trying to play a DVD on my computer. First i thought i needed a new decoder which i downloaded and now the error message and resulting "support" is saying I have compatibility issues between the decoder and my video card. Where is my video card? Any thoughts?
