To be honest, it turns out I actually have the same problem with the the burned discs and ISOs when playing on Leawo, even though I didn’t think so before. Everything works fine unless you try to skip to a different part of a title, using the slider, navigation buttons, or chapter menu. Then the image freezes as the sound continues.

Perhaps its a glitch in the ISOs themselves? 😦

In which case, it would be a pretty major bummer, but I’m still going to look on the bright side that these sets even exist at all.
