I put the latest install of MorphOS on my eMac, and I've noticed that when I'm playing a video and try to resize the window, that my whole system begins to lag until I stop resizing the window. It's as if I'm trying to play videos on a 500Mhz AMD system with 128Mb or RAM.
And yes I've tried high and low quality videos, the results are always the same.
First, I assume you mean moving or resizing a MPlayer window.
Since it's totally smooth here, I think it just means you're almost out of video ram when it happens (you have 32MB video ram?). MPlayer itself allocates video ram for the overlay surface, so when you're out of vmem, it can get really slow.
So, if you didn't already, i strongly suggest you disable enhanced mode for the related screen. Also tell us what kind of screen resolution you use.
