It seems there is still a endian bug with Xv:
playing movies requesting a YV12 colorspace show wrong colors (usually green
people). It's the same for both xv ports.
For me (NV34 on ppc), it can be fixed by applying the following patch:
--- nv_video.c~ 2008-01-21 11:33:53.000000000 +0900
+++ nv_video.c 2008-01-21 19:02:27.000000000 +0900

if (e) {
unsigned short *vud = (unsigned short *) vuvud;
-#if X_BYTE_ORDER == X_BIG_ENDIAN
- *vud = (vs[0]<<8) | (us[0] << 0);
-#else
*vud = vs[0] | (us[0]<<8);
-#endif
