I have been looking.

I find mention of an STM chip that doesn't appear to be generally available yet --

Nero appears to have the necessary IP for sale:

This runs at 200 MHz for HD. This would tend to indicate that a dedicated chip is the best solution since the current Ti DSPs would need to run at at least 1 GHz.

Interesting manifesto from Altera:

"A state-of-the-art DSP running at 1 GHz cannot perform H.264. HD decoding"

Will look more tomorrow.  Have to go to a meeting tonight.
