I was watching the Ice Age trailer the other day and it seemed choppy to me. Is this something that the DSP should be able to render flawlessly?

So how much is the DSP core really being used?

If it is not yet fully implemented yet, what improvements can we expect as newer firmware moves more processing to the DSP (if it does)?
Video player and audio players use solely dsp. There is at the moment an ongoing discussion on the developers list on whther the processor would actually perform better in video decoding task than the dsp and whether some other dsp algorithm would be better for mpeg4 decoding than the current one used.

I don't think dsp is used in much else besides those stated above. Might be used for jpeg decoding as well.
