The patch didn't applied cleanly to CVS version of vp3.c:

patching file `vp3.c'
Hunk #8 FAILED at 2351.
Hunk #9 FAILED at 2359.
Hunk #10 FAILED at 2370.
Hunk #11 FAILED at 2381.
Hunk #12 succeeded at 2681 with fuzz 1.
4 out of 14 hunks FAILED -- saving rejects to vp3.c.rej

After applying remaining changes manually and testing
/MPlayer/samples/V-codecs/VP3/vp31.avi I saw no improvement.
