[gentoo-user] DVD Playback Problem

[CJoeB]

Hi Guys,

First, let me say that I did search this problem on Google.  I found a 
somewhat relevant solution, but before I try it, I thought I would post 
here.

The problem is jerky playback of the dvd when I try to play it using 
kaffeine.  The laptop on which I am trying to play the DVD is a Dell 
Inspiron M1710.  It is less than a year old (purchased late April 2006).

One of the things the post said was to check that dma was enabled by 
running hdparm -I /dev/hdc.  I did that and this is the output:

/dev/hdc:

ATAPI CD-ROM, with removable media
    Model Number:       TSSTcorp DVD+/-RW TS-L632D

    CBLID- below Vih
    Device num = 0


Another thing this post said was that the person  switched from the 
scsi/sata system for the drive to the deprecated ide/sata model.

Admittedly, I haven't rebuild the kernel in a while.  I'm running 
2.6.21-gentoo-r4.  This was because when I tried to upgrade to the next 
stable version of the kernel after 2.6.21-gentoo-r4, it wouldn't 
recognize my hard drive as a sata, so I went back to a kernel version 
that I knew worked.  Do you think a kernel upgrade would help solve the 
problem.

BTW  I have 2 gig of memory on this laptop, so the issue shouldn't be 
memory related.

Any ideas?  Thanks in advance for the assistance!  :-)

Regards,

Colleen
