I downloaded ubuntu-6.06.1-dvd-i386.iso and verified the md5sum against that listed at the download site.  I then burned the DVD and got no errors.  One nice thing ubuntu has in the 6.06 release is a menu option (on booting the CD/DVDs) to verify the CD/DVD content.  When I tried this, it shows errors for some files.  
<br><br>Surely there could be a problem with the burn, but I was wondering if there is any way to md5sum the DVD?&nbsp; The only thing I could think of is to make a .iso from it and I do not know if that would even be expected to reproduce the original iso and match its sum.
