Nice but I noticed two problems with my RV530:
1) the new attributes have effects only when BICUBIC is 0, but not when BICUBIC
is 2 but disabled because the image is not scaled;
2) with a small video (512x368) I noticed a 8% speedup (with mplayer -benchmark
-quiet -nosound filename) no matter XV_SYNC, with a larger video (1280x720) I
noticed a slowdown (over 61% and the video is jerkily), unless XV_SYNC is
disabled, where I get the same performance. But maybe this is a collateral
effect of the XV_SYNC that must paint all the frames and is noticeable only
when doing benchmark (i.e. fps > video refresh)?
