Netflix lag on Apple Tv 3

Hi guys!

I am running Netflix on the Apple Tv3 via ethernet capble through my Timecapsule working as the router.

My connection is 20/2 and is giving me no other problems in others terms of use.

I have just bought the new Phillips 55PFL8007T 3-D tv, and I have it connected to the Apple Tv through HDMI caple. The TV displays Full HD 1080pi.

All devices is placed no less than 50cm. apart.

NOW MY PROBLEM is, that when i am watching movies or series on Netflix, i am somethime experincing small rapid lags in the picture, going on for about 3-5 seconds, befor stabilazing again.

It happens with a couple of minutes interval, so you can imagin how irritating it is to watch anything on netflix.

The lags have, besides the irritaitions, another result, that the picture don´t match the sound and subtitles after about 30 minuts. Seems like the lags is causing a time difference in the picture.

I can stop the movie, and start it from where i left of, then the picture match the sound and subtitles....for antoher 30 minutes.

Please help.

Thank you.
