Observations:
Works well on the iPad. Max bitrate is 1024 kbps so quality is not razor sharp, but acceptable when full screen. This is through wifi on my home network. Have not tried setting it up to stream through the internet. (I want to keep my bandwidth for Netflix!)
Have not tested on iPod Touch, but will later today.
On the PC, the quality is OK. Would be nice if bitrate could be more than 1024 kbps.
For me, it does exactly what I want it to do, and is a great value for $12.
Install Note:
Do not install off the CD. Download the WinTV Extend update, put the CD in the drive, and run the update. It will "look" at the cd to makesure you have a 7.2 CD and install the letest version.
