[MPlayer-users] yuv4mpeg identical frames

[Caj Zell]

Thank you Catalin,

if I understand your hint correctly, you are telling me this is due to the 
stream being interlaced?

But (in that case, excuse me otherwise and please hint me further),

1. is it really reasonable to assume that the top and bottom half is 
exactly identical on a bitlevel?

2. isn't it strange that other interlaced movies I play do not show this 
behaviour?

Best Regards,

Caj Zell
