And again, it's just sat there.
Right now, the biggest bottleneck in video decoding is RFBI bandwidth (i.e. the bus between OMAP and the LCD controller we use), being too slow to push more than ~15fps through at 800x480. Beefing up the processor-side decoding doesn't help. We've been working on this and the next firmware update will give you significantly faster video (with a couple of caveats). So it's mostly just down to the large image display, which more or less suffers from the same problem. I don't think it would give us much benefit at all. As for PowerVR stuff, we're certainly well aware of that internally. Cheers, Daniel
