(eg. DVD, DV) - Totem, mplayer, xine, vlc, avidemux, kdenlive, they all

This is not a physical limitation of the laptop - these programs all
worked fine under Feisty. It fell apart with the Gutsy upgrade, I
believe. mplayer can play DVDs (barely) with the -vo x11 option (this is
an xv problem), but the laptop doesn't really have the snot for that - I
need this graphic chip working.
The laptop has a SiS chipset. Since I last posted on this subject, I
have done a fresh install of Ubuntu Hardy. Interestingly, there is now
no reference to SiS in xorg.conf at all. Looks like Xorg is doing it all
automatically, clever wee thing:
$ grep -i SIS /var/log/Xorg.0.log
(--) PCI:*(1:0:0) Silicon Integrated Systems [SiS] 630/730 PCI/AGP
...
(--) SIS(0): VideoRAM: 8192 KB
(II) SIS(0): Using 4096K of framebuffer memory at offset 0K
(--) SIS(0): Hardware supports two video overlays
...
I've attached the rest of the log. It kind of all looks OK to me, but
I'd be interested to hear if anyone can see any trouble in there.
Thanks,
Douglas.
Xv is the preferred output. From my googling:
1. Can you allocate more memory to the graphics card in the bios?
2. Does it work to run at a lower resolution during video playback - I
know this is not ideal but how good are your eyes anyway?
3. Does turning off the MIT-SHM extension off help?
4. Does -vo sdl provide an acceptable response?
Thanks, Nick, but no good yet:
1. Can't set the video memory from the bios - it seems to be
permanently set at 8Mb
2. Lower resolution didn't help - not even 640x480
3. Turning off MIT-SHM didn't help
4. SDL didn't help
I've reattached the xorg.0.log, just in case anyone can spot any trouble
in there. Is it OK that it says "Using 4096K of framebuffer memory"?
Douglas.
