This isn't the scientific method. If anything has been proven, it's  
that this is all far from scientific. I agree, from what I've seen,  
the test done by doom9 is hardly the end-all-be-all test that will be  
the final word in MPEG-4 codec bench marking.

No, your point (from what I've been able to piece together) was that  
you didn't like doom9, or anything from that page. You also had major  
disagreements with the testing methods, the way the tests were  
conducted, and the way everything was published. You feel that many  
mistakes were made (possibly purposefully) that lead to an inaccurate  
comparison. I'd say your point is pretty well made.

AVI, given its limitations, isn't that great of a container either.  
However, it's widely distributed. Hell, it's MPlayer's default output  
format. And that still doesn't solve the problem that not all  
programs output to AVI. Besides, the container has little to do with  
the CODEC in use, and the CODEC is what it's all about. I think the  
choice of MP4 wasn't because it was a great container, just a common  
one. If people wanted great containers, we'd see more Matroska and  
OGM files floating around, instead of AVI.

You're correct in this case. Just out of curiosity, can MPlayer  
output to MPEG4-ES? Perhaps we could establish some benchmarks of our  
own, based on that.
