He says he has it stacked on a Toshiba HD. Load time is somwhat faster. Build quality is lighter and seems less substantial than the Toshiba. He couldn't get Fifth Element to load. Terminator loaded, though, and he says the PQ is superb, as close to film as he's ever seen. PQ of House of Flying Daggers less so. PQ of an upconverted SD is at least the equal of the Toshiba. Second person says upconversion is "somewhat soft". He did have a problem with lockups. Looks like BD has its share of bugs.
