	Actually, per my understanding, xa_rle.c only handles the
Microsoft flavor of RLE, which only has 4- and 8-bit variants. Looking in
the XAnim source, the file xa_qt_decs.c has Apple's flavor of RLE, which
comes in *7* variants (1, 2, 4, 8, 16, 24, and 32bpp), believe it or not.
The latter is what I'm going after.

	VP3, as I understand it, is supported in MPlayer via a Win32
codec. This is suboptimal, particularly when the VP3 sources are open. If
I have this situation incorrect, someone please let me know before I hurt
myself on the code.

	No, it's a different video codec; I'm sure of that. I'll certainly
upload samples if I get both decoders operational.
