[theora] mpeg -> theora fastest encoder

[Mihamina (R12y) Rakotomandimby]

Hi,
I would like to convert, as fastest as possible, some VCDs tracks to 
ogg/theora.
In older times, we had single core CPUs and the higher was the frequency, the 
faster the job is done.
Now, with multicore CPUs, encoding is not always spread on all the cores.
I even encounter slower encoding with the firsts coreduo than on single cored 
AMDs.

So, do you know if there is any mpeg to theora encoder that is able to fully  
handle SMP?

Thank you.
