Chromecast resolution reset issue (I think)

Hi!

I've recently bought a chromecast, and it works quite well. There's just one issue: Every once in a while (once every 5 min?) the screen resolution seems te be reset, video cut out but audio still running, and when the video goes back up it shows the 'resolution screen' in the right top corner of the screen. I'm using a Pioneer VSX-529 and a D-vision television. The chromecast is hooked up directly into the a/vreceiver.

Thanks in advance, -Fly
