As of DVD Catalyst 3.84.5, DVD Catalyst includes profiles for the new Google Phone, the Nexus One.

To watch movies on the Nexus One, just download and install DVD Catalyst 3, select Android > Nexus One from the dropdowns on the left, insert your DVD or drag your video files onto the program, and click Go.

Files created using the iPod/iPhone profiles will play fine on the Nexus One as well.

For additional tips and tricks on how to get the best quality video on your Nexus One, just refer to the “Droid” articles on this website. The only real difference with video between the Nexus One and the (Verizon) Droid is that the Nexus One has a resolution of 800×480 vs the Droid’s 854×480.
