What is the difference between all the Divx iDCT selection?

[SuperCyrix]

AMD x87 iDCT
AMD 3dnow iDCT
AMD 3dnow hybrid iDCT
MMX iDCT
Reference iDCT
Fast interger iDCT
Miha's x87 iDCT
Miha's x87 Reference iDCT
Optimized MMX iDCT

So what is the image quality, speed, and filesize between the various iDCT can someboy tell me?
Thanks

From my experience, the AMD ones give junk frames every now and then, so I dont bother with it. The others seem to be fine for me, never putting out bad frames, and the image quality is, as far as I can tell, identical. It comes down to speed and you cant beat Miha's fast x87 iDCT for speed. Coupled with XMPEG 4.5 using YUV, I get 40-45 fps, nearly double what FlasK gives me with the same setup.

Thanks, I never heard of XMPEG I'll check it out.

You all suck. Use FlasK and XMPEG both suck
DVD Decrypter to copy from DVD
DVD2AVI to iDCT and demux the audio track
AVISynth to frameserv
VirtualDub for encoding
Nandub for muxing and splitting
