On the Epia back/frontend I allways used --enable-xvmc, but a closer
inspection revealed this results in a build against XvMCW.
I just recompiled SVN with --enable-xvmc --xvmc-lib=viaXvMC which
makes no difference (since the update), that means: playback is smooth
but I still need to have hue at 50% for normal colors.
I have no problem with this, except that I can imagine that first-time
users could be daunted by this phenomenon at first sight?

The laptop thing is even stranger: I recompiled with --enable-xvmc and
--xvmc-lib=I810XvMC and now the logfile tells me myth can't use xvmc:

2006-06-11 16:04:42.596 VideoOutputXv Error: XvMC output requested,
but is not supported by display.
Xlib:  extension "XVideo-MotionCompensation" missing on display ":0.0".
Xlib:  extension "XVideo-MotionCompensation" missing on display ":0.0".

The Xorg.0.log however tells me something different:
(II) LoadModule: "extmod"
(II) Loading /usr/lib/xorg/modules/extensions/libextmod.so
(II) Module extmod: vendor="X.Org Foundation"
        compiled for 7.0.0, module version = 1.0.0
        Module class: X.Org Server Extension

(II) Loading extension XFree86-DGA
(II) Loading extension DPMS
(II) Loading extension TOG-CUP
(II) Loading extension Extended-Visual-Information
(II) Loading extension XVideo
(II) Loading extension XVideo-MotionCompensation
(II) Loading extension X-Resource

Which clearly shows that "XVideo-MotionCompensation" was loaded?
Anybody seen this before/have an idea? (google doesn't reveal much useful).
