I have the SOLO and Charter HD cable. When watching an HD channel, the picture is full screen (16X9) on both my laptop and my Droid. It is a higher quality picture than when watching a standard definition channel. When watching a SD channel, the picture is 4X3 with black bars on both sides on both my laptop and Droid. The picture quality is OK, but not as good as with an HD channel. I am perfectly happy with the SOLO. I went with it because of price and the fact that I don't have the computing power recommended for the Pro-HD. I also only have 2 mbps upload speed. I recently experimented with 3 mbps but cut back to 2 mbps due to cost. I also have two source devices plugged into my SOLO. One is a Charter cable box and the other is a ROKU for Netflix. The cable box uses component cables and the ROKU uses a composite cable. I use splitters to feed the two audio sources into the single pair of R/L audio jacks on the SOLO. I use the ROKU to watch Netflix on my Droid since there is not a Netflix app as of yet for the Droid.
