I watched too last night with the patch using mediacodec however I had 
it on old AVSync but the finish early issue still existed which is 
strange too.

Will have to repeat tonight with AVSync2.

I can make some programs available again if it helps Peter. Use my 
previous link but use recordings/1020_20190228080000.ts (news last 
night) or some of the other recent ones. The one listed is guaranteed to 
show the issue. 1020 is HD and 1021 is SD.
