Comcast offers a free Comcast Mobile app for iPhone/iPod touch devices. It offers access to your Comcast services and version 2.0 includes remote DVR functionality, as well as other new features.

Now Comcast has a new video out today demonstrating its new version of the app, including the remote DVR function.
