200 char lines are a bit much... Any how, that kind of performance dropoff would indicate that Bernhard's suggestion that the MMX optimizations are not being used. When mpeg2enc starts up do you see lines like the following? INFO: [mpeg2enc] SETTING 3DNOW and EXTENDED MMX for QUANTIZER! INFO: [mpeg2enc] SETTING EXTENDED MMX for MOTION! INFO: [mpeg2enc] SETTING MMX for TRANSFORM! INFO: [mpeg2enc] SETTING EXTENDED MMX for PREDICTION! If not then the MMX/3DNOW instructions are not being used and that will cause a major slowdown. It sounds like the cpu detection isn't working right on your system or 'nasm' isn't installed so that the assembly portions can be built.
