Did this easy test and can confirm !!
First Downloaded "finding Puppy" , real 24p-file, shown as 24 in Mede8er when pressing info.
Then watched end-credits from Dark Knight, being a 23,976 .m2ts. (End-Credits are easiest way to check, very easy to catch it)
Shows 23 when pressing info on Mede8er. Selected 1080p50Hz for my Sony HW-10.
Yes, every 40 seconds there is little hick-up as file obviously is running a bit to fast? , not 23,976 but 24
So Mede8er-guys - please test it on your own and please go back to Realtek then (assuming you can confirm, but I am confident you will)
