Windows 7 AIO Best practices?

Hi, i tried making a Windows 7 AIO DVD using a program called "Win7 AIO Maker" which i got when i googled for some automated ways to do the task above. But even before using the software, i tried the imagex commands to make one and successfully burned one to a dvd. After testing all editions(x86 and x64) installations worked fine. But then, the OS installed from this AIO DVD hangs, slows down dramatically and even fails to install programs and some hardware such as audio stops working.

so i'm just wondering if there are ways to make sure if a burned/copied windows 7 dvd will install a "reliable" OS.

i also used this tut.
will this also enable the use of x64's recovery options?

ok. Thanks! :]

oh and 1 last question.
Upon using the ei.cfg utility,
does it do anything else to the .iso other than delete the ei.cfg file?

+rep! Thanks bare foot kid!
