I have tried the netflix app in my sylvania 7" minitablet it works  but the tablet cant quite handle the video feed and it is quite choppy. the sound comes through well but the video freezes and skips. One thing that I did like was I did not have to enter a code as an external device like I did with the DVD player. It went right to my account the same as a computer would do.

After having a very difficult time getting a netflix app for my Sylvania 7" tablet I decided to post a link to a mediafire page with the Netflix 1.7 app for android. If you have an app you cant find or are having difficulty downloading respond to this post and i will see if I can find the app you need and will put a link to it for you on here.
