Acer Revo XBMC with Ubuntu video jutter - hottech956 - 2010-04-24

I have successfully installed XBMC w/Ubuntu on my Revo 1600 using THIS tutorial. However when I play a 720 file, (mkv or mp4) I still get a video judder. I have also tried doing a custom xorg file using this tutorial. Any ideas on what else I could try? I do not know how to get the logfile to post it, but I will look on how to do it so I can post it.

When you press the "o" key during playback to see the codec info, does it say VDPAU somewhere?

- hottech956 - 2010-04-24

yes it does. dc:ff-h264_vdpau

With vdpau and a proper xorg.conf it should run smoothly... Maybe somebody else can give some advice here.
Could you upload a video sample that doesn't play on your system?

My xorg look like this.

Code:
Section "Device"
        Identifier "nvidia"
        Driver  "nvidia"
        Option  "NoLogo"              "true"
        Option  "DynamicTwinView"     "false"
        Option  "FlatPanelProperties" "Scaling = Native"
        Option  "ModeValidation"      "NoVesaModes, NoXServerModes, NoVertRefreshCheck, NoH$
        Option  "UseDisplayDevice"    "DFP-1"
        Option  "ModeDebug"           "true"
        Option  "HWCursor"            "false"
EndSection

Section "Screen"
        Identifier      "screen"
        Device          "nvidia"
        SubSection      "Display"
                Modes "1920x1080_60_0" "1920x1080_24"
        EndSubSection
EndSection

Section "Extensions"
        Option  "Composite"           "false"
EndSection

You need to turn on debug logging and restart xbmc to get a debug log.

Here is my DEBUG log with it enabled

I upgraded from Jaunty to karmic, I used THIS to install XBMC and config the xorg file. I still get a judder on the videos. When I play a video and press "o" I do see "dc:ff-h264 ". I have the 190nvidia drivers.What else could I do to address the judder?

Do you run XBMC in Gnome or do you boot directly into XBMC.
I have a REVO r3610, and when i run xbmc from Gnome do it lag like hell, but it runs smoot if i run xbmc as my x session directly.

- hottech956 - 2010-07-05

it boots directly into XBMC

Would setting the GPU to 512mb make a difference?
