[MEncoder-users] mencoder fails to read files created by dvgrab

I am trying to move recordings from my Digital8 camcorder to my computer
and encode them with x.264. So i grabbed the recordings with

  dvgrab -a -srt some-recordings-

which seem to work fine. The resulting files are played fine with vlc.
But mencoder seems to have a hard time with those files:

  jw at raven:~/dvgrab> mencoder -ovc copy -oac copy -o t.avi Tanz-Jan019.dv
  MPlayer dev-SVN-r30099-4.4-openSUSE Linux 11.2 (x86_64)-Packman (C) 2000-2009 MPlayer Teamsuccess: format: 0  data: 0x0 - 0x3e7e4a80
  MPEG-ES file format detected.
  [V] filefmt:27  fourcc:0x10000004  size:0x0  fps:0.000  ftime:=0.0000
  videocodec: framecopy (0x0 24bpp fourcc=10000004)

It then hangs, just eating CPU.

When I try to play those files with mplayer, some of them can be played,
others not. However, none of them can be handled by mencoder. The files
that can not be played with mencoder, give me:

  jw at raven:~/dvgrab> mplayer Tanz-Jan019.dv
  MPlayer dev-SVN-r30099-4.4-openSUSE Linux 11.2 (x86_64)-Packman (C) 2000-2009 MPlayer TeamCan't open joystick device /dev/input/js0: No such file or directory

  Failed to open LIRC support. You will not be able to use your remote control.
  Playing Tanz-Jan019.dv.
  MPEG-ES file format detected.
  FPS not specified in the header or invalid, use the -fps option.
  No stream found.
  Exiting... (End of file)

Please notice, that vlc can play this file just fine.

Any ideas?
