Mum is living in Tokyo for a couple years, and the voltage will fry her TV. She doesn't want to get another one since she just uses iPad anyway, but she'd like to be able to watch DVDs. Is there any way to do this since you can't connect a disc drive to an iPad?
Yes. Most projectors have various video inputs and most dvd players have outputs that would correspond (Example: HDMI, RCA cables, component, etc). The one problem that you might run into is the audio as some projectors do have speakers but even these are usually very small and not loud at all. To solve this she could easily get some external speakers similar to what you find commonly used with a desktop computer.
