To fix this issue try to manually assign some of the movies to a different Titleset.
[ Right click on the Movie -> Assign To Titleset ... ].
Movie length and Xine
(e-mail from 'the5' sf.net )
I looked all over to solve a problem I was having using mplex. The videos I was encoding would show incorrect lengths in xine and qdvdauthor after I encoded them with mplex. The source of the problem turns out to be that xine and others require constant bit rates, and only make an estimate of play length on variable bit rate movies.
This set of excellent emails goes into the details of the problem. http://email@example.com/5427584.html
The quick fix. Encode your mpeg2 output with a constant bit rate that is supported (6600kbps,9800kbps are some that I use). Then when you use mplex add the -C parameter to force a constant bit rate output.
mplex -f -C in.m2v in.mp2 -o out.mpg
That should do the trick.
( Note: you could also use MPlayer which does a better job estimating the run length )
Have problems loading older project files.
Due to a typo in the xml file you will no longer be able to load older project files. To mitigate this you should run the fixit.sh - script. You pass it as its first argument the name of the old project file.
E.g. > fixit.sh myproject.xml
ERR: Cannot pick button masks
This error can occur if you try to generate a DVD with an old project file that has Text buttons.
This was fixed in Beta 0.1.0. To make your DVD work you will have to recreate the buttons ([Unbutton] then [Define as button]) or to completely re-create the DVD.
**ERROR: [mpeg2enc] Could not read YUV4MPEG2 header: stream requires unsupported features!
This is a Problem with the mjpegtools version 1.6.2 and above. To fix this add "-S 420mpeg2" to the ppmtoy4m command.
Note: There seems to be an older version out which requires -S 420_mpeg2. Please either upgrade or use the 'e' buoon in the CommandQueueDialog, to change it for your system.
To compile 'Q' DVD-Author you need only the qt libraries Qt 3.x and above BUT below 4.x.
