Okay, I made a test stack with a player and a slider with playRate from 
-2 to +2, current Thumb position 1 that on scrollBarDrag set the 
playRate to the thumbPosition and opened a mp4 video a tested.

1) Under LC 9.6.6, changing the playRate can cause LC to hang, whether 
the video is playing or paused. Not every time, but some of the times it 
would just pop up an endless spinning windows cursor ball and Windows 
would declare that LiveCode 9.6.6. was "not responding" and a forced 
quit would be required.

2) When it did work, I was able to change the playRate to 1.2 or 1.4 and 
while the video sped up, apparently my ears are better than I thought, 
as even I could tell the pitch got higher (the people's voices got 
higher pitched and "squeaky")

Windows 10 (latest build) LiveCode 9.6.6 STABLE.
