Well, I'd like first to thank Vudu team for such a great product they created! I received my unit about 10 days ago and am quite happy with it after a week of active use and 6 movies rented.

Lack of WiFi connectivity, was the missing feature, I noticed first. I ended up connecting my Vudu through wireless, using a device, named Squeezebox as a wireless bridge. So, while important, lack of Wifi isn't a deal breaker for me. I know some other folks expressed the same concern.

I'd like to suggest addition of the following functionalities that, I believe, weren't discussed so far:

a. Audio/Video synchronization. Sound and the picture were in a perfect sync when both autio and video were streamed through analog outputs. However, I see noticeable de-synchronization after the video output is upgraded to HDMI (audio is still connected through analog stereo output). Having experimented with many DVD players I know that this issue is not that unusual. I've seen it in almost any of 6-7 DVD players tried in recent 2-3 years. Most of players (if not all of them) provide an on-screen control for manual adjustment of audio/video delay. Such a control would be very handy in Vudu

b. Calibration. Lots of folks who care about picture and sound quality use special calibration DVD disks that contain images and sounds records for proper adjustment brightness, contrast, tint, stereo balance etc. Two most recognized calibration DVDs are "Avia Guide to Home Theater" and "Digital Video Essentials". I have the Avia disk, but, unfortunately, can't use it with Vudu. My suggestion is either to provide special calibration screen in Vudu software or, even simpler, make calibration DVD(s) available for rental/purchase through Vudu.
