Following my post last week, I've been doing some more with this. As Clayton suggested, I recompiled Mplayer from scratch. If I start gmplayer, I can add mp3s or oggs to a playlist and play them OK. If I run: mplayer -ao alsa9 -vo xv -dvd 1 -dvd-device /dev/dvd the film starts OK, with good sound. However, if I run the same list of options with gmplayer instead of mplayer, I get the message about the PC not being fast enough to play this. The relevant console messages are attached. I then tried Karol's rpm, but this refuses to launch, with a message that it can't open .VMG info. Again, the console messages are attached. In the event, I have got Xine working, athough it does its usual thing of not playing direct from the GUI - you have to go to the dvdnav submenu and select one of those. I'd still like to follow up why MPlayer isn't working as expected, though, so if anyone has some good lines of inquiry .... Thanks Kevin
