Comment 14 for bug 245794

I wanted badly to contribute with my feedback regarding this stressing bug.

First of all, I've never seen such issue before (7.x, 8.x). Recently I decide to download and burn Ubuntu 9.04 (DVD), sweep old installation and install the new one from the scratch.

I've burned the dvd on Verbatim DVD+R (then I've tried also Sony DVD+R too, on slow speed) - in both cases dvd image burned ok (md5 sum is ok too). I've used check disk integrity (via Ubuntu menu when you boot from the DVD) and I get *no* errors.

Then I've tried to install the OS, but I've got the same error every time on the same place (34% in my case when you goes in graphical mode) and then I can't do anything than start installation from the scratch.

Once I've tried to install in text mode (via text menus) and everything was ok (i.e no errors like those) but I wasn't able to configure after installation the OS to start in graphical mode (it seems too much work to do the proper settings, what I normally receive with graphical installation, so I give up and installed without any issues the old version 8.10).

So, on the bottom of this story I'm pretty sure that the DVD media is burned ok (proved with text mode installation), but it seems that graphical mode installer has some glitch that prevent at some point proper installation.

I really need badly that this bug will be fixed in future releases (9.10?). Maybe reading method (DVD driver) does not try to use crc1/crc2 to recover. I mean that you can read anywhere this disk on any OS without read errors, but not in the installer.
