KG20041209 Error log more obvious visually, but still incomprehensible, even to developers of product. Fixed: 3.0.0

KG20041207 Header 'fields' now sticky, stay where you put them while movie plays. Changed: 2.0.5
KG20041206 Title-bar proxy allows quick Finder access to bitstream under analysis. Added: 2.0.5

KG20041204 New Aqua-ish GUI and PAL ergonmics. Fixed: 2.0.5
KG20041203 Demuxing a VOB segment file that is not #1 yields a stream that cannot be analyzed. Fixed 2.0.3
KG20041202 Segmented VOB files cannot be easily demuxed as a complete set Open
KG20041201 Dragging .m2v file to toolbar icon yields 'frozen' screen. May play, but menus, buttons yield only SysBeep() sound. Fixed: 3.0.0
KG20041130 No sequence_start_code at beginning of .m2v file means MPressionist cannot open. Fixed: 2.0.3
WR20041126 MPressionist does not scan file beyond sequence_end_code Fixed: 2.0.3
KG20041125 First packet in Program Stream demux not put into elementary stream. Fixed: 2.0.3
KG20041124 MPressionist has two Quit menu items. Well, we nailed this in MegaPEG.X, but missed it in MPressionist. Fixed: 2.0.1
WR20041123 Sequence header change that alters frame size or rate is not recognized. Fixed 2.0.3
KG20041122 HDTV file type detection may incorrectly tag elementary stream as a transport stream when stream does not begin on start_code_prefix. Fixed: 2.0.3 Different menu options allow for direct opening of any stream type or demux.
KG20041121 2:3 Pulldown detector may report small# of false positives. We haven't found any cases, but we found the bug. If you see a break in the cadence, there probably is one. Open
KG20041120 Dragging file to MPressionist Dock icon yields two open document Windows, but only one can be used. Fixed: 3.0.0
KG20041119 MPressionist.X may not display last picture in sequence. Fixed in Pro:2.0.1 HDTV:2.0.2
KG20041118 MPressionist.X may fail to detect type of mux stream (for demux) when stream does not begin with valid 32-bit start code. Open
KG20041117 HDTV: Macroblock inspector is modal, prevents access to underlying screen. Improved: 3.0.0.
KG20041116 IDCT selection change applies to newly decoded frames only, not frames in GOP buffer. Frames are stored completely decoded (Y'CrCb). To evaluate IDCT, change while video is playing.
KG20041115 Arrow key navigation forward and backward in time only works after clicking in the thumbnail row. Open
KG20041114 Seeking to start of open GOP may result in strange artifacting. Now you know why multi-angle requires closed-GOP. If problem appears, seek to one GOP earlier than the GOP of interest and play forward.
KG20041113 HDTV version is slower than Pro version. Open: Pro is gathering less data than HDTV (no block-data). Also, it would appear CFM/PEF executable faster than Mach-o.
