Is it possible to access my recorded programs remotely?

No, not the ones on your DVR if that's what your asking.  You can go here: Home - AT&T U-verse to view shows but they take about 3 to 5 days to show up after airing.

You could also look at something like this: Slingbox.com - Slingbox Home.  You can watch shows from your DVR with this gear.
