Yes, typically there is no issue after few seconds or few minutes, but when I try to stop a 42 minutes lenght tv-series episodes few seconds before the end during the credits. I know , it isn't good , I'm a developer too sorry
I don't know after 5,10,15, 30 or 35 minutes but around 41-42 minutes I'm sure as you noticed from the log. I will try to stop play with these time frequency
I use MePo since a long time, several years, with no issue with custom evr video renderer
addendum: also remember that I start from 1080p50 fresh rate so madvr typically perform a refresh rate change to 1080p24 or 1080p60 (if madvr smooth motion is active) and back to 1080p50 on stop
