12.04.2 Install Disc Fails After Entering Name & Password

view story

http://ubuntuforums.org – My Mythbuntu 12.04.2 64-bit DVD fails on install on the screen right after I enter my computer name and password. I tried burning another disc and it fails at the same exact point. Is my ISO bad? Is there a recommended disc burning program that will verify the burn? I think I used KB3 the first time, then Brasero the second time. It seems like Ubuntu and Mythbuntu discs often fail - it would be much better if there was an easy way to verify the download and burn right away rather than finding out in the middle of a long install.
