[MPlayer-users] Isolated EVO video problems

[phillong69 at netscape.net]

With the google summer of code E-AC3 contribution 
http://forum.doom9.org/showthread.php?t=129050  (thanks!!!), I've had 
good success with mplayer and command lines such as

./mplayer -vc ffvc1 -demuxer lavf -fps 24000/1001 -ac ffeac3 -aid 3  
/movies/BLUE_PLANET_DREAM_ALIVE_HDDVD/HVDVD_TS/feature_BLUEPLANETVC1_HD1.EVO 


However, I've had a problem with Norbit and Black Snake Moan which report:
Forced video codec: ffvc1
Cannot find codec matching selected -vo and video format 0x3267706D.

Trying to force AVC instead of VC1 with -vc ffh264 gives:

Forced video codec: ffh264
Cannot find codec matching selected -vo and video format 0x3267706D.

The audio works fine on these (with -vo null ...)

As it's an HD-DVD it must be VC1 or AVC, right?  (Unless it's MPEG-2 
which would be dumb but no problem to detect and play), and AVC is well 
supported so I'm scratching my head.

Any hints/suggestions?
