hi
i'm using linux in two pc
1) desktop with pentium 400 mhz mandrake10.1
2) laptop with pentium 1100 mhz mandriva 2006

on the second pc i have poor performances
about the video card (trident cyberblade )
dvd play slow down...the same dvd play well on the first pc...

the trident driver belong to xorg libraries installed with the rpm suffix i586...

the question is : if i'm able to find on the network the driver source file,then recompiling it with specific parameters for my architecture,does will improve performance ?
if the answer is yes,then what i have to set to recompile with optimim performances ?
i'm able to build spec files,does rpm will
provide itself right parameter to compile with performance optimization ?

thanks in advance

Pentium II 400MHzPentium III or Pentium M ... you're doing well!You'd expect it to be the other way around wouldn't you? What do you mean "slow down"? You get pictures in slow-motion or you get a lot of freezes and skips?Manrdiva probably has a driver rpm in it's repositories too. However, there is more to dvd playback than the driver and video-card.Compiling kernel and drivers for your exact system will usually result in improved performance. There is not enough information to advise you on this, very large, subject. The best distros for this sort of thing, if you are game, are probably slackware and gentoo.

However, I would suggest you try some other form of video playback before you start fiddling - if an ogg/theora file will play OK, then we start looking askance at your dvd drive (for eg). Maybe you have hardware which is breaking, maybe there are some settings needed (like enabling DRM for a dvd drive) which will improve playback. Maybe you need updated codecs? Maybe just a different software player?

A good way to get a comprehensive check is to run the xine-check script.

Aside: your English is pretty good considering some obvious difficulties - you are expressing yourself well and with some confidence. It can help people talk to you if you edit your profile to include a "location". I'm guessing Malay or similar, but I may be way way off base

Hi

english is not my mother tongue ..i'm italian ..i will apdate my profile...

i avoided to write the whole story to not bore people and to avoid to mislead ...

the second pc pentium III intel celeron coppermine 1.100 mhz with trident cyberblade video card shows a discarded frames whe n playing dvd..
xine-check runs fine..
i followed also all the suggestions in the xine official site...
i buils also a scipt to launch only X graphical system and xine...(no kde or gnome),but the verbose option of xine shows me skipped and discarde frames...(the skipped are more than the discarded)...it seems the audio and video goes out of synch ...
i tried also to rip chapter to hard disk and play from file but the situation is the same

so i thinked to recompile video drivers and kernel
to see if the situation improves...
i need an help to set the compile parameters to obtain max speed results with my cpu...

then if someone is experiences with xine an has some other hint or tips i will appreciate too ..

thanks in advance

Frame skips usually mean you need dma enabled for the drive.
Ripping from dvd will reproduce the skips in the copy - you need to take a mpeg movie with a camera or download a video. Preferably ogg/theora format as mentioned. You must remove the dvd drive from the equation.

Maby you should swap the dvd drives between the two machines?

Hi

dma is enabled
unfortunately the second pc is laptop and the first is a desktop,so drives are not swappable.

That leaves trying out a video file that doesn't involve the dvd drive anywhere in it's creation ... you could rip from the good drive on the desktop and transfer the file to the laptop?

If recompiling the drivers actually improves this issue, I'd be surprised.
