I'm not sure it's helpful to keep linking to this. It's important  
historically, but Monty's whole thesis about "start decoding here and  
you're good" is WRONG because of the continued packet issues.

To clarify, the seeking algorithm he describes is inaccurate. This  
message is an accurate description of the rationale behind the split/ 
granulepos hack for encoding both the timestamp and the back pointer  
in the granulepos, as is now used by theora, dirac and cmml.

Ups! Maybe it's time somebody corrected that statement then - the wiki seems
the right place to put the correct algorithm, IMHO.

Cheers,
Silvia.
