Netflix app crashes on Sony TV - what to do?

On my Bravia 32W705B crashes the Netflix app very often.

Netflix smears when loading a movie that has already started or after two seconds when loading reaches 99%. Likewise with "new" films during the intro (with the studio name, so also after one to two seconds). I do not get an error message, because simply switched back to the normal television.

This happens as far as I notice only in movies, as in series with an episode length of 25 minutes a complete season in a row is not a problem. Reconnecting to the router and "refresh internet content" did not help. Have already ergoogelt that I'm not an isolated case, but real solutions have not yet found.

Do you have any?

Do a complete system update. Had a similar problem with Samsung and then helped.
