Just received my copy of VERTICAL LIMIT:S.B yesterday.Have been listening to both DOLBY DIGITAL and DTS tracks carefully and not to miss observing video quality as well. The most outstanding audio track,goes to DTS5.1 surr. with its achievement in more deeper and stronger bass and more enveloping music score presentation. On video quality,the picture is clean and sharp,really lives up to the expectation of SUPERBIT name. While playing the disc,i've encountered a minor playback hiccup.During 45th minute to 46th minute,there is one scene suddenly jerks a bit.I thought that it was the layer change,but no,several minutes later at 50++mins,after SCOTT GLENN finished his sentence,the picture freezes for a short while.If this is a layer change,how about the earlier one?WHAT IS THAT? On the audio,the explosion that kills "KAREEM" and "PETER" nearly blows off the woofer of WHARFEDALE DIAMOND 8.2 fronts.Subwoofer is recommended for this track.
