Netboot 20070308ubuntu40 fails to install system

[bart1452]

Compaq Presario SR1550nx with 3400+ AMD Athlon 64 processor, 1 Gig ram, 200 GB hard drive, Light Scribe DVD/CD R/W. Windows XP is already installed so I am installing a dual boot system. Windows was defragmented and checked for errors before attempting to install Ubuntu.

Downloaded the Ubuntu 8.04 64 bit LTS net (minimal) install ISO image for #20070308ubuntu40 (image number found after pressing F9 in the boot menu.) Burned the CD at 16X. The computer booted successfully into the installation program. I used the default installation settings except for the Ubuntu partition size was set to 83 GB. The retrieval of intial components from the server was very slow, like the it was waiting a long time in que for each component. After guided partioning completed, base system began downloading and error "Failed to download base system" appeared with 6% base system downloaded. On second try - "Failed getting release file" error appeared with 8% downloaded, and subsequent errors like "couldn't download Aptitude" and for a lot of other packages. Several tries made and all failed. I chose "Abort Installation". This was the most recent attempt after failure a few days ago.

I expected it to go smoothly the same as the 32 bit system did on my laptop. I also tried installing from the live CD 64 bit Ubuntu 8.04 that I burned at 16X. It seemed to hang in the middle of the process. I did not try running the system from the live CD first.

Trying to run the live 64 bit CD on the computer the screen filled up with:
[xxx.xxxxx] (rapidly ascending numbers) followed by:
SQUASHFS ERROR SBBREAD failed reading 0x7c1df size a4e7
UNABLE TO READ PAGE, BLOCK 1f06d996 size a4e7
I cut the power when the [xxx.xxxx] reached something like [467.xxxx]

The box "In what package did you find this bug?" in this report form did not display the choice of packages for me.

To continue, I think I may have found the problem. I tried downloading the live desktop 32 bit ISO from different mirrors and burning a copy on my DVD/CD burner and each time it reported 3 errors. Trying to run it gave me the same errors as I reported above for the 64 bit CD. I downloaded the same ISO to my laptop which successfully runs Ubuntu bit 8.04 and it burned the image with no reported errors. I put the disc in the DVD/CD burner on the desktop and it again reported 3 errors. I transferred the disc the CD-ROM and it reported no errors. The disc played fine on that drive and I am using the live CD right now to report this in Firefox. The problem is the DVD burner.
