I just bought a 4-tuner Tablo and am having the same issue. As soon as I cast the video to the TV, my progress bar goes to 0:00 and FF or RW take me back to the beginning. If I stop casting, the progress bar goes back to normal and I have control again. So what I’ve had to do to FF through commercials is to stop casting, FF to where I want to be and then restart casting. Obviously, this is not a good solution. I don’t currently have another device to use.
The Tablo is on firmware 2.2.8. The tablet is a Lenovo Yoga 2 running Android 5.0.1. The Chromecast is one of the original models running firmware 1.17.46278. I assume this is up to date. I don’t see an option to update it.
Is there any update for this issue?
