Tested on Vanta (0x002c) on Linux 2.6.0-test5, X 4.3.0 (pre1v1 from
 Debian), nv and nvidia drivers. But not out-of-box.
First, I needed to increase RIVATV_MAX_ORG_WIDTH (1024 works for 672x288
 movie). 720 - crashes. By changing rivatv_overlay_colorkey, it worked 
with depths 24, 16, 15.

0x002c - Vanta (NV06 => NV04 arch)

According to DirectFB driver, you can support YV12 on archs >= NV10, by
using pitch|1<<16|0x00100000 on setting NV_PVIDEO_FORMAT for archs>=NV10
(cannot test. I have only Vanta :)

Dunno, if using YV12 is possible for NV04, but if you change 0x011 to
 0x111 on line 668 (when setting NV_PVIDEO_OVERLAY (KEY_ON, VIDEO_ON,
 FORMAT_CCIR)), you will select yuy2 output format :) (tested)

So uyvy isn't really problem :)

I see another problem: vidix API must be expanded to pass bpp to vidix
 driver (for rivatv_overlay_colorkey). Also dunno, if BPP <15 or >24 are
supported by all cards. (IIRC RIVA128 didn't support even 16bpp).

There is another problem. I couldn't get it work with vesa:vidix and
fbdev:vidix. (vesa:vidix plays, but video isn't shown. trying setting
colorkey to r=0,g=0,b=0, uncommenting block, and trying different
bufferdepth's gave nothing). 

Anyway, thank you. Good work!
