When I demux a PVA stream with either ProjectX or PVAStrumento I get a DVD with good audio sync. But in the process of demuxing both ProjectX and PVAStrumento chops up the 27 minute PVA stream to 23 minutes. When I demux in ProjectX with video error correction disabled I get the full 27 minutes demuxed but the DVD becomes hopelessly out of sync. Playing the PVA stream by itself with the original timestamps intact, the video naturally plays perfectly in sync. Is such a time deficit to be expected and acceptable with what I think is a nasty PVA stream? Or is there another method of authoring a DVD from such a stream without having it chopped up this way?
