That all sounds reasonable to me. I am a programmer, and though I'm not familiar with the internals of WinUAE, it seems logical to me that the memory that WinUAE uses to hold each frame can't be re-used for the next frame until that frame has been at least copied into a buffer somewhere to be flushed out to disk. If you were running at 50 - 60 fps, it seems to me that would be an awful lot of memory that would be required in order to hold even 1 seconds worth of data. If you think about how long it should take to copy each frame to a buffer, compress it and flush it out to disk, I don't think it's surprising at all that there would be a slowdown. If you could simply copy all the frames to a buffer and do the compression and writing to disk later you might be able to speed it up a bit, but you'd need TONS of memory in a hurry.

Of course I could be completely off base here - maybe there's a little leprechaun inside WinUAE that does all this stuff magically, and he's just dawdling to piss people off.
