Mplayer 9.0: Videos are wavy lines?

[Dj-Icer]

I have download the M$ Media player version 9.0 from the net on my old computer, Intel Celeron 500Mhz, 384 of RAM, old graphic card and with built-in sound.

This was never happen to my new computer (P4), but when I try playing short videos that I download from the net, the video turn in to weird wavy lines; like a rainbow color. The sound are all right, but just the video. But some videos works fine. Just few videos doesn't.
What's the cause of this?

I have, installed Realplayer 10 and DivX. Did the DivX decoder messed it?

However, I went to Media Player 9.0 option, and go to 'performance' tab and click on advanced. I clicked on 'use overlays' then OK. When I got back to play the video again, there were no more 'rainbow wavy lines'. But some videos runs not very smooth. The picture frame was kind of slow.

What happened here now? Thank you all in advance if you're willing to help

Makes sense. Overlay support is generic and well supported by most any video card manufactured in the past eight years. The slow down is due to the Celeron 500MHz processor. If you are trying to decode MPEG-4 with the DivX decoder's post filtering enabled, then you are likely to see noticeable drops in frame rate, especially with video encoded at higher resolutions.

The DivX decoder is not optimized very well IMHO. Drop the DivX decoder in favor of ffdshow....

....as it is a highly optimized MPEG-4 decoder. Assuming you keep the post filtering set low, ffsdhow can playback MPEG-4 at decent resolutions on a even an deprecated K6-2 system. Try that with the DivX decoding engine.

you sure its not the visualizer?

I mean, after I have set 'use overlays', there were no problem about those wavy lines. The next thing I experience, some videos turn to slow frame rate. Probably the cause of my Celeron 500. I don't know but I think you're right RobRich.

I'll download that DivX codec and see if it works when I got back home at 8 pm Thanks Rob.
