I have quite a few of my BD's backep up onto my HDD's, and I'm going on a long trip, so I decided to copy some to my laptop and watch them with Power DVD9. Most viewed fine, but some said that they couldn't be seen on my virtual drive. All were ripped with anydvdhd and them compressed with BDrebuilder. I know there is an issue with unprotected iso's playing on some blue ray software, but most of my rips play ok.
