How do you get movies onto your Inc.?
I too would love to know the answer to this.
There may be other ways, but the Droid will play .mp4 videos beautifully. If you have movies in some other format, look for a video converter capable of converting to .mp4, and the Droid will play them.
Anything "iPod/iPhone/Zune HD" formatted will play extremely well on the incredible.
You can torrent any video for those devices and drag them onto your Incredible. That or if you use a program called "Handbrake" it can convert a DVD to .mp4 for you.
