Playing DVD's smoothly

I am using Ogle GUI version 0.8.5 to play DVD's,but the movie doesnt play smoothe (i.e. it freezes for half a second then continues to play and freezes again,the whole time).I already switched to Window Maker because it uses less resources than Gnome or KDE,but it still doesn't run smoothly.Does anyknow know how I can make it run smooth?Can I stop alot of the other applications running in the background (just having X and ogle running)?Or is there another DVD player,which is better?
Under Windows I can play dvds normal,so my hardware/dvd disc is okay.

first you should check if your dvd-rom drive is dma enabled.
use "hdparm" for this (for checking and enabling!)

i am using mplayer for freeBSD - no problems playing dvd. i also tested xine for linux, no problems either...

sometimes you need special X extensions or drivers to make dvds run smoothly. most times not.

how many MHZ do you have?

I have a 1 Ghz amd,and dma is turned off,because hdparm /dev/dvd outputs this:


I have tried hdparm -d1 /dev/dvd,but I get this error:


If you mean Xvideo (xv),then I have that extension.
Btw,I have also tried mplayer,but I have the same problem,so it must be the dma.

You need to get the right driver installed to activate DMA.
what chipset is your mainboard using? (IDE)
VIA or SIS? (i guess since most intel chipsets are supported out-of-the-box....)

I would say via,because cat /proc/ide/via returns this:

cat /proc/ide/SIS doesnt work.

uh oh, "82c686a"...

this is a broken chipset (hardware failures!), maybe there is no way to activate DMA.... (not sure!)

did you check transfer speed? ("dd if=/dev/hdc1 of=/dev/null bs=1024 count=1024000" for a 100MB check)

Do you mean "dd if=/dev/dvd of=/dev/null bs=1024 count=1024000" (because /dev/dvd is my dvd thingy?
It returned:

are you working as root? (because of the localized error messages...)

please remove your locale settings (probably in your /etc/profiles or /root/.profile), or translate this: "Invoer-/uitvoerfout" for us into english...

and for the /dev/dvd, it should not matter. /dev/dvd should be a softlink to /dev/hd??

you get an error message accessing the dvd drive? don´t use a video-dvd! they are read-protected! use a dvd that has no protection, best a data dvd, for testing.

your throughput should be constantly far above 10MBit/sec=1,2MB/sec. (use "date ; dd... ; date")

also, i had a "0" too many in the blocks count. this check would load 1GB, not 100MB as expected, please remove one. (then it could also work with your dvd-rom since it just read 180mb without problems)

any new results?

Yes,I am doing it as root.Sorry for the dutch messages,it means "input/output error".
"In" means "in" and "uit" means "out".

It does matter?Because with your command I get this:


I only have video-dvd's

"dd if=/dev/dvd of=/dev/null bs=1024 count=102400" outputs this:

yeah m8, you were supposed to measure the time this command takes

It varies,the first time it was 33 and the second time 29.So its,around 30.

[note]
... i am not getting any notification messages anymore from vBulletin hope i miss no post..
[/note]

30seconds would make about 3.5MB/second
this is more than enough. but we can´t tell from this if this datarate is constant. try this: copy the dvd to your hard drive. open the "vts_01_0.ifo" in your dvd player and see if it works then.
if yes, it IS the DMA mode, if not, you probably have CODEC problems.

What do you mean with copy the dvd to your disk?Its 7 GB big.

so?
i meant it like i said it...
this is (imho) the only reliable way to now find out if it is a graphics problem or a dvd-rom problem.

Okay,I assume that I can just copy it with Nautilus?Or do I need some special commands?
