PS3 MPEG4 AVC - RGB or YUV?

[Colmino]

This question differs from the one I had before (I ultimately decided that the only real solution will be to render the whole thing off as a 1TB raw).

The video I'm going to be encoding for playback as MPEG4 AVC on the PS3 is coming straight from After Effects CS3. Not only does AE3 only deal with video in RGB (at least according to what I've read), but all of the elements I am dealing with are in fact RGB raws, and they all take full advantage of the 0 to 255 luma range. In fact that was one of the main points behind my project: to make sure the videos were covering the full luma spectrum.

YUV, of course, is meant to stick to a luma range from 16 to 235. If the video exceeds that range, then depending on how one's devices are set up, the values above and below that range are likely to be clipped, resulting in crushed whites/blacks. That's how I understand it.

Here's what I'm hoping to learn:

1) When it comes to encoding MPEG4 AVC for the PS3, there are two options which work: Xvid2PSP and Megui. Both reportedly offer templates which ensure that the encoding process will not generate a video that the PS3 refuses to play. What I don't know is:
a) Does the MPEG4 AVC standard (as the PS3 likes it) support RGB video?
b) Will either of those two programs encode RGB video?
c) If not, what are my options? I mean, will I have to convert the video to YUV before encoding it?

2) a) What procedure am I going to have to undertake in order to ensure that every last bit of detail in my video (currently RGB with luma detail fully covering 0-255) gets encoded without crushing the whites/blacks, gets played by the PS3 without crushing the whites/blacks, and gets displayed by the tv without either crushing the whites/blacks or doing something stupid like taking the original luma range and displaying it as 16-235, with correspondingly light blacks and dark whites?
b) Does the PS3's "superwhites" option have any control over this? (Or any other menu-enabled option, for that matter.)

That about covers it. Cheers!

I'll post back if I find anything out. No dice, so far.
