Could someone please help me figure out what I need to do to play DVD’s on my computer. When I purchased the computer it did not have a DVD player so I bought a Pioneer Internal DVD/CD writer and installed it. Everything appears to be running ok but when I put a DVD in, I get an error that says I need MPEG-2 encoder/decoder. Is this something else that I will have to purchase or can I download for free. I have also been told that I simply need to update my video card (since there was never a dvd player before). Help, I just want to be able to watch DVD’s from my computer. Also, I tried to watch the DVD on WMP11. I get an error there that says something about changing my display settings. Any advise would be helpful.
