HTPC + AT&T Uverse + Tuner Card

[Stridulent]

Performing a typical google search turns up a lot of bad news to those that would like to use their HTPC to view AT&T Uverse IPTV. I am interested in this as football season is around the corner and AT&T is the only cable offered in my area.

I need Uverse to be streamed through my HTPC in HD so that it can be displayed on my projector screen. This screen isn't the standard 16x9 resolution, as it is 2.35:1, and the HTPC is required to make the video output fit the screen.

I'm not really concerned with recording on the HTPC itself. I have heard of rumors that you can get specific TV tuner cards with IR blasters that will work with AT&T Uverse, but I would like to know of one that is proven to work before I start investing in anything.

TL;DR
Need AT&T Uverse to play through my HTPC in HD



EDIT: Major +1's if this card could work with an Xbox 360 as well (for the same screen size reasons). Not having any latency issues through a tuner card would seem pretty unrealistic.
