Yes and no. The controller prevents us from using the IVA (well, perhaps more accurately, made Nokia decide not to use it—for whatever reason), which would help a LOT with video decoding, but there's also things involved with the controller that impact the efficiency of decoding (someone with better knowledge of mplayer could speak to this more completely than myself), so just because it's pegging the CPU doesn't tell the full story.

Well, since the stock kernel drops CPU to 330MHz when DSP is in use, you'd actually get worse playback.
