If you don't mind, I would like to ask what your ping/latency time is. speedtest.net or pingtest.net lets you do that.
Does your internet speed slow down when you're taping 1 HD show and watching another?

Yes, our speed slows from around 18 to 12.5, but we have another connection through another provider that handles any large download needs; 25Mbps+.
 Not that 12.5 can't handle large downloads. Actually, we rarely use anything other than UVerse for downloading. Very solid download and upload speeds.
