hello every body
I had ubuntu 10.10 on my laptop but it couldnt play movies with good quality.
which distribution of linux has the best graphic performance for whatching movies??
My VGA Card is ATI x1400

the distro is irrelevant. If you can describe in a good amount of detail what "couldn't play" means we should be able to help you.

That video card is no good, so I wouldn't expect good performance. I don't think the distro matters much in this case. What driver are you using now anyway ? radeon or fglrx ?

i mean when im watching movies,almost every 2 minutes the movie stops for a second and then continues

I had windows seven and the quality and performane was good but not in linux.
im using fglrx driver

im using fglrx driver

what app are you using etc? throw us a bone please...

Im using the default playe of ubuntu that is mplayer

Hard to tell for sure (confusing product pages, etc) but it seems like the x1400 has UDV/ATI Avivo which is meant to offload some of the video decoding from the CPU to the GPU.

You might find that XvBA/VA-API will fix the problem....or you might find that it doesnt.

*edit- ubuntu isnt exactly fast either. A lighter distro, or a lighter DE (eg xfce4, NOT 'xubuntu-dekstop') will work better.

*edit, x2- fglrx? With a x1400 on 10.10? You sure about that? AFAIK the last versions of ubuntu that would work with fglrx and a x1400 was 8.10 or so.

ok, so what is the output of mplayer in a console? if it's dropping something, I'd guess you're using a horrible video output by default.

You are not using fglrx. 'radeon' is your only viable option. It provides no acceleration for video playback beyond Xv (though with gallium3d it does now support XvMC, but that probably won't make it into most distributions for another 6 months at least).

However, a pause for a second every two minutes does not sound, to me, like your CPU can't keep up. Definitely try playing a video file with mplayer from a terminal and see what errors are produced.

Hmm, could be many things. Is the CPU running at 100% ?

Try using the '-cache' option for mplayer, for example 'mplayer -cache 8192', or 'mplayer -cache 8192 -cache-min 50'.

no the CPU is running less than 20
but Im new to linux what do you mean by using the cache option???
what should i do ???
thanks

Open a terminal where the movie is at and type in:

then press Enter. Or if you're using the mplayer gui, check the options for a cache option and put in a larger cache.
