Sorry I didn't introduce myself earlier. My name is Gary and I purchased a Vizio Co-star from Walmart last week. We own Vizio TVs and were satisfied with them, so bought the Co-Star after some extensive research. I had previously used HDMI to connect my laptop to the TV for watching ESPN3 and FirstRowSports.eu for tennis, cycling and hockey broadcasts. Also used my Son's PS3 to watch some of the feeds, however Sony and ESPN do not get along so no ESPN3. So far I am happy with the unit with a couple of nit picks. The HDMI passthrough is not passive so the unit has to always be on if other household members just want to watch "vanilla" TV. Internet speed tests show that its network adapter performs poorly compared to my laptop when running 100Mbps ethernet. So far this forum and its members have been very helpful.
