Hello,
i try to convert a video mpg2.ts to avc.mkv or mp4 or avi, with same definition (720*576 anamorphose to 16/9 (1024*576); convert to 1024*576), but each time preview is \"cut\" see picture.

For 640*630 definition, there no pb.

I committed a workaround, disable assembly when source height=target height
It will be slower but will work
No idea what\'s wrong, i\'ve re-read the code multiple time, it happens only when MMX/MMX2 is activated

In fact all acceleration are disabled when source height=target height
I dont think sse is used much for rescaling
