Comcast recently added the myDVR Manager to my area. This lets me view, schedule and edit my DVR recording online. The same feature is also available on their iPhone App. Scheduling recoding from the iPhone app is way easier than their DVR’s UI but it needs more refinement.
The search results for shows leaves a lot to be desired. It has no filter to show HD programs only. Most of the time it shows only the standard def. results. Hope they fix this soon. Also I can not wait for their iPad app.
