First...on TiViMate

1. While recording shows with TiViMate, does it has the stay on the same channel which is recorded or I can browse to another?
2. Does PVR works even with TV on Live Channels or - might sound stupid, with TV turned off - as Sky Q does?
3. How to change recordings directory from default (on TV) to a connected USB device?

Second round on accessibility

1. Can't access it. I need it to remap buttons and to activate Twilight.
2. Is there a workaround to get to accessibility or a program that gives me access to it?

Third...sound on my TV - Saba/Changhong, is...crap! I can't get a right settings to make it work. Sometimes voices are lower than music - in movies, sometimes is sounds to be in a stadium. Tried every possible setting and I can't get it right. I don't want to hook up a soundbar, even if I know that I ultimately need to.

Fourth Sometimes I need just to make the screen black but leave the voices on. Is there an app?

Thanks.
