JVC> I've read all the doc's thoroughly, google'd 'till my brain hurt, tried
JVC> all the options I could find in the man page (-framedrop, -cache,
JVC> -double, -nosound, etc.), I have DMA enabled on my drive, and I've tried
JVC> all the latest dvdread (0.9.1, 0.9.2 and 0.9.3) and dvdcss (1.2.0 and
JVC> 0.0.3ogle3) packages as well as uninstalling those and using
JVC> libmpdvdkit: the result is always the same, slightly jerky video for
JVC> DVDs. AVIs play fine--a little out of sync, but I can adjust that.
JVC> Which brings me to my other problem. All of the above pertains to the
JVC> xv driver. I thought maybe I could get better results with one of the
JVC> gl options (which were compiled), but Mplayer crashes when I use those.
JVC> I've included some output below along with my system spec's. With gl I
JVC> get a half second of sound, then it hangs for several seconds and
JVC> finally crashes. With gl2 I get a little piece of sound and then it
JVC> crashes immediately. You'll note from my spec's that I have a GeForce2
JVC> (GTS) card. I know the doc's say Mplayer is "known not to work" with
JVC> it, and I know how you feel in general about Nvidia and their drivers. I
JVC> tend to agree, but this is my card, it's a popular card, and it does
JVC> well most of the time, so my wish is for someone to actually try and
JVC> resolve this here. It ALMOST works, and I have a good system for
JVC> testing this, fast hardware, and a newly installed LFS OS with the
JVC> latest software (or the sanest: gcc 2.95.3 and automake 1.5). I have
JVC> the latest Nvidia drivers installed, 1.0.2960, with Nvidia's headers
JVC> linked in /usr/X11R6/include/GL/, but I've also tried using the utah-glx
JVC> driver with MesaLib 3.2, and that didn't help. Neither did SDL. The GL
JVC> modules just won't go. Perhaps Mplayer is using some advanced GL
JVC> feature that my card is choking on, or perhaps this is a bug in Mplayer.
JVC> I've spent much time on this and tried many things, for it is my one
JVC> desire. If I could get smooth DVD video with Xv, I won't cry about the
JVC> gl bug; but maybe GL is my key, and I just need a workaround or a
JVC> patch. Maybe Xine is using GLX successfully, and that's why it plays
JVC> smoothly. I dunno. Here are my hardware spec's:

I don't see anyone answering it, so I'll make my own silly suggestion
:) - try -cache <something in kb> to enable cache and see if it
helps...Just don't make it unreasonably big - I think that 256kb is
more than enough for any case...I once had to use such thing when I
needed to play movies from a _slow_ harddrive while having lots of
disk activity, and it helped, though I don't know how useful it will
be to DVDs - never used it, but I guess that there could be the same
problem as with some CDs - scratches and therefore slow or no reading.
