OK - this is super WEIRD!!!
I've just noticed when I use Chromecast from my iphone to my TV and play a movie trailer from my movies on my EMBY library, the movie trailer does not play, but instead a video file from my music collection plays instead (an R.E.M music video).
When I disconnect from my Chromecast connection and try the movie trailer again, it plays perfectly on my IPhone.
This ONLY happens when I am Casting to my Chromecast device.
It plays the same music video for all my movie trailer selections (any movie I choose when Casting). But when I disconnect from Chromecast the trailers play fine.
This was working perfectly over the past few days.
Any ideas folks? This is super weird.
Thanks Rob
