If your house set top boxes where set up on coaxial we recently discovered that many users can connect an ethernet cable to the back of their cable box and get internet. So try connecting an ethernet cable from you box to your blu-ray player and see if that does the trick. If not you might try to just connect you laptop to the back of you uverse box to see if at least you have internet.

Let us know the result, I'm sure other users would be curious to know.

Awesome, this leads me to believe it will work with slingbox as well but I have no official confirmation. I have never heard this featured advertised with AT&T and no it doesn't work with some other providers. Let's hope AT&T doesn't jack with the set up because I think this is one of the advantages of having IPTV.

premtek,  do you mean when try watching U-verse in another room while your streaming netflix/blu-ray content? Seems like if your streaming netflix there is no reason to watch tv unless your meaning other house users in another room. I'm curious to know this as well, I don't have the netflix roku and my blu-ray doesn't have BDlive so I can't test either. Hope some post on this because I'm curious as well. I did however test using the internet connect to a set top box and watch uverse at the same time and didn't have any effect that I could tell to my eye, seemed flawless.
