SuSe 8.2, DVDs play jerky

[83mercedes]

I know my dvdrom is OK, cuz dvds play fine with Mandrake 9.1, but in SuSE 8.2, whether using mplayer or ogle, the dvd video and sound is kinda jumpy or jerky, it will play fine for a couple seconds, then sorta hesitate, then play again, etc etc. Almost acts like my machine is too slow or not enough memory, which is not the case.

Cannot get an error message, anyone else see this?

Thanks.

I think you have to have hdparm installed to have these files, but you can check if dma is enabled with it/them. Here's my dvd-rom (Debian)

funky formating :? :lol:

You can be sure it's your dvd with

localhost:~# cat /proc/ide/hdc/model   

DVD-ROM BDV316C

localhost:~#

see if

localhost:~# cat /proc/ide/hdc/driver  

ide-cdrom version 4.59

localhost:~#

Doing what you say as root:

 

linux:/home/mike # ls /proc/ide/hdc

. .. capacity capacity driver identify media model settings

linux:/home/mike # /proc/ide/hdc/settings

bash: /proc/ide/hdc/settings: Permission denied

linux:/home/mike #

 

I am root, right? Now what am I doing wrong?

Thanks

Oh, guess what, I enabled DMA in YaST, Hardware, ide DMA mode, an BOOM it works good now!!! I so love SuSE.

Thanks!

Great! For future reference you did

/proc/ide/hdc/settings

and forgot 'cat'

cat /proc/ide/hdc/settings
