Your DVD could be timing out while communicating with the video chip.

Check to see if your video allows for xvideo overlay by running the "xvinfo" command in a Konsole. If you get a page or more of info it does. If a line or two, it doesn't.

Also, make sure you have DMA set on your DVD drive:
hdparm -d /dev/hdx
replacing "x" with the drive letter of your dvd. If it's on that is ok.
Otherwise, you should turn it on by typing
hdparm -d 1 /dev/hdx
where "x" is the driver letter of your dvd.
You may want to add this command to a startup script such as /etc/rc.d/rc.local to ensure that the DMA support is active every time your computer boots.

If those don't help then you may have a dvd firmware problem.

Cheers for that again.

"xvinfo" returns a good couple of pages.

"hdparm -d /dev/scd0" returns;
HDIO_GET_DMA failed; Inappropriate ioctl for device.

As I recall, at the beginning of this thread there was a boot from cd problem that went away with BIOS tweaking. It is likely that the same BIOS change that cuased this problem to start with was not entirely reset. Can you control the use of DMA for a drive in the BIOS? Have you set it to something?

No, no BIOS tweaks used.
The BIOS was all set correctly.

I got the install cd to work by trying again and again. Eventually it worked.

There are no DMA settings in the BIOS.

Thanks neeway.
