I've been on the 1HD/3SD profile since I had Uverse installed in June. Tonight I was looking at the System Resources and noticed that it had changed to 2HD/2SD (it changed overnight). According to Uverse Realtime the Downstream rate is 19,192 Upstream is 2040.
Obviously AT&T changed something to allow the extra HD stream..?
I did see some U-verse techs mention on another forum that AT&T would add another HD streams to the existing profiles. The 19/2 stream would receive 2 HD streams, the 25/2 profile would receive 3 HD streams and the 32/5 profile would receive 4 HD streams.
