Since the October 15 Update the skip and fast forward for recorded shows does not work any more with Chromecast. When I run the app without casting to the Chromecast stick it works fine. The moment I start to cast, begin and end times of the recorded show display as 00:00 in the app. If I pause, the correct time of the show displays on the TV shortly, but not on the app. If I then try to skip or fast forward, the show goes back to 00:00 and starts all over.
So it is impossible to play a recorded show and try to skip / fast forward. Casting works from the Chrome browser on the PC.
I was able to reproduce this problem on two different HTC M8 and a Nexus 9 tablet.
