Hi all, as i posted in http://forum.xbmc.org/showthread.php?p=1...post132669 I'm having trouble with playing many dvd's in xbmc. The dvd menu navigates fine but after a minute or so of playing it start skipping and jumping forward.

All other players play them fine including dvdx, xboxdash, windows media player, zoom player.

As suggested by Elupus I've tested with VLC and indeed it shows the same symptoms, in that at the same point as xbmc VLC just suddenly stops and returns to the title menu.

I'm to understand that this is not an mplayer issue but a dvd player issue. However I fail to understand which dvd player is included in xbmc other than mplayer. Ultimately I need to find the root source of this, I mean where the actual source code is developed and maintained and collaborate with them. I just as yet don't understand who/where that is.

VLC log is included below.

[elupus]

we have our own dvdplayer, it's build ontop of codecs like libmpeg2 and libavcodec. also using libavformat for demuxing.

since vlc fails, atleast we know it's nothing specific to xbmc. they use the same dvd navigator (libdvdnav) as we do. so the "bug" is in that.

I say "bug" cause it's more likely just a broken dvd. (some bytes wrong). libdvdnav is quite sensitive to that sort of stuff.
