Anyone here have much experience with dvd-author and/or dvd-slideshow I am having a few problems with both (at the moment I am driving them from qdvdauthor, but the same issues seem to be present even if I do it from the command line) I am trying to add background music (in the form of an mp3 file) to the VMGM menu (main menu) I am trying to (or at least qdvdauthor is trying to) do the following mplex -f 8 -o "menu.mpg" "menu.m2v" "song1.mp3" Where the m2v file is a MPEG2 stream of my menu background, the mpg file is the output that goes into DVD author and song1.mp3 is the music I want. At this point I get ERROR:[mplex] File song1.mp3 unrecogniseable! mp3 file is a straight 192kbs file that seems happy enough in any player I chuck it through. dvd-slideshow I am running the command dvd-slideshow -o show -f list.txt -n Photos list.txt is a test file with entries as follows imgp1364.jpg:5:: imgp1365.jpg:5:: and so on.... When I run this I get the following in the output messages [mpeg2enc] Could not read YUV4MPEG2 header: stream requires unsupported features! Any help offered would be greatly appreciated. Wayne
