No, video playback is integer only. Using float is way too slow.
The only float code in MPlayer is iirc in one of the audio filters.

Nothing at all. We dont use any borland compiler, gcc is afaik even on
windows the compiler to use. Beside, the last section rather looks like a bug 
in windows or the Delphi libs than anything else. FPU exceptions should
always be handled apropriately by the right application if enabled.
