I have never ever had any problems with mplayer (atleast not with gentoo because of all the extra codecs you get) so i would bet on the movie is fucked or something..

Mplayer prints out alot of messages all the time so if there is a error you should see it.. you can problably make it more verbose too :roll:

The error that I see is that my CPU is too slow for the medi and/or the drive may be to slow. It suggest some way to fix it but its not working ...

so, it could be so that indeed the cdrom drive is too slow.

Try to copy the file back to your drive to see whether it works still from the harddrive.

Maybe you don't have dma transfers enabled on your cddrive. Enable it with

Sorry but in my experience RTC doesn't speed up zilch. Here is what (in my opinion) should be done to find out what really is slow.

1 - copy the movie on hard disk. If it isn't slow then it's cdrom's fault. Otherwise go on...
2 - mplayer -vo help; check what is available. Try fbdev under the console, sdl, xv and gl/gl2 under x, the latter only if you have 3d acceleration. Disable sound. Do not rely on your eyes only, instead use -benchmark to find out exactly how many frames are being dropped. The command looks like this:
mplayer -vo sdl -ao null -benchmark <filename>.
If the movie feels smoother with one of those video outputs then you've found out that it's a video card/video output choice issue. If it's smoother with ANY of those then it was the audio. If it still isn't smooth:
3 - Do: mplayer -vo null -ao null -benchmark <filename>. This way you'll be benchmarking only the codec used and the data throughput (but we already know it's not a throughput issue). So if it still isn't smooth it's the codec.

I hope this helps you. Let us know about what you find out.
