[MPlayer-users] bad performance playing DV type 2 files

I'm having terrible performance playing DV type 2 files.  Does anyone
have any suggestions for speeding up performance?  I think it is using a
Microsoft DirectShow codec.  Is there a different library for DV videos
I can use or a different codec to download?  I can play DIVX movies full
screen with no problems.

Also, the DV movie has lines through it.  Do I need to de-interlace or
anti-alias the video?  Can this be done on the fly while playing?

Athlon 1Ghz, Mandrake 9.0, mtrr, mplayer 0.90rc4

Thanks,
Michael

Here is my -v output when I play the movie:

Possible reasons, problems, workarounds:
- Most common: broken/buggy _audio_ driver
  - Try -ao sdl or use ALSA 0.5 or the OSS emulation of ALSA 0.9.
  - 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 -hardframedrop.
- 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.
Read DOCS/video.html and DOCS/sound.html for tuning/speedup tips.
If none of this helps you, read DOCS/bugreports.html.
