IMHO, the #1 reason to use ISOs instead of playing non-ISO rips from the hard drive is that, if you want to play HD DVD movies from another computer on your network, you no longer have to map the hard drive locally in order to get the HD DVDs to play with PowerDVD Ultra 7.
I also agree with others that, after inserting the disc while AnyDVD HD is enabled, you should exit AnyDVD HD and then create the ISO so that you get the full disc without modifications. Then if an error is found in AnyDVD HD, and fixed in a subsequent release, you can re-rip the ISO because it's just like the original disc.
