The reason why DVDs don't run well is because the software that 'decodes' them generally requires a processor speed of 800Mhz or greater. If you do want to run DVDs then you will need an old piece of hardware called a DVD decoder. This is a plug in card that has a dedicated chip on it that will take the load from the processor and will enable all the fancy DVD effects such as in a window etc.
