[MPlayer-users] Karaoke (cdg) support broken?

I get an interesting error when I play the audio file along with the CDG
video file:

mplayer ~/Karaoke/test.cdg -audiofile ~/Karaoke/test.mp3

I've tried the items suggested in the error message as best I can figure
out, but maybe this makes sense to someone? My system definitely shouldn't
be too slow, it's an i5 CPU with 8 gigs of RAM.

Error message with new warning appended:

           **** Your system is too SLOW to play this!  ****

Possible reasons, problems, workarounds:
- Most common: broken/buggy _audio_ driver
  - Try -ao sdl or use the OSS emulation of ALSA.
  - Experiment with different values for -autosync, 30 is a good start.
- Slow video output
  - Try a different -vo driver (-vo help for a list) or try -framedrop!
- Slow CPU
  - Don't try to play a big DVD/DivX on a slow CPU! Try some of the
    e.g. -vfm ffmpeg -lavdopts lowres=1:fast:skiploopfilter=all.
- Broken file
  - Try various combinations of -nobps -ni -forceidx -mc 0.
- Slow media (NFS/SMB mounts, DVD, VCD etc)
  - Try -cache 8192.
- Are you using -cache to play a non-interleaved AVI file?
  - Try -nocache.
