I've understood that the IVA2 component of the omap3 CPU is entirely undocumented, and that there are some third parties which have been supplied documentation on it, and have created an enhanced decoder capable of 720p decode, and is selling it at enormously high cost. Uncompressed 720p requires about 40 megabytes per second. The flash certainly can't handle that, and I don't even know if the bus that the camera is connected to can handle that much
