DVD Play Speed

[karlp at ourldsfamily.com]

RH v8, Intel system (on a slower AMD system this isn't an issue)

If I play a DVD on my DVD drive (/dev/cdrom1), it's choppy and uneven
whether I play it with gmplayer or ogle.

If I

dd if=/dev/dvd of=file.iso

then play it using either, it plays nicely.

Is there a problem with the IDE drivers? I have a scsi disk as the primary
drive. So, I copied it to an IDE drive on the same system and it still
played fine.

Any suggestions might be useful, if I can understand them, or even
implement them.
