I have installed XBMC Live Dharma Beta 3 on the hdd of my revo 1600. Performed the following steps.

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install nvidia-current nvidia-current-modaliases nvidia-settings
sudo wget http://pastebin.com/download.php?i=f5f9654bb -O /etc/asound.conf
sudo wget http://pastebin.com/download.php?i=f2e38265 -O /usr/share/alsa/cards/HDA-Intel.conf

DTS and Dolby Digital capable receiver is true. Audio, audio output device, and passthru device set to hdmi.

It plays videos perfectly with no stuttering.

Then I installed XBMC Live Dharma Beta 4 on the USB stick. Performed the same update of nvidia drivers. Same video/audio settings. But videos are stuttering and dropping frames like crazy.

Both version has the same driver and version number as shown below.

xbmc@XBMCLive:~$ cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX x86 Kernel Module 260.19.12 Fri Oct 8 13:22:24 PDT 2010
GCC version: gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5)

I Have pasted two debug log from both Beta 3 and Beta 4. Please help.

Beta 3 log. http://pastebin.com/71zKVvWR
Beta 4 log. http://pastebin.com/4s0DWHRZ
My guisettings.xml file (same in beta 3 and 4). http://pastebin.com/FMD3Ubfc

VDPAU is broken. Could you please try an install without the x-swat repo?

Thanks. Tried another fresh install with no nvidia driver upgrade and there is no stuttering. But the AAC sound problem is back http://forum.xbmc.org/showthread.php?tid=84234 and that was the reason for updating the driver as suggested in http://forum.xbmc.org/showpost.php?p=634934&postcount=7 which worked with beta 3 but not working with beta 4.

How much memory do you have in your box. There is a bug in the current nvidia drivers that cause them to use over a 1gb of memory. I spent ages tracking down the cause of this. The do have a fix for it, but its not released yet - if you step back to an older version of the driver all is good again.

1GB :-(. Working fine on Beta 3 with the same driver. I guess I would stick with beta 3 for now and will try final dharma build on usb stick before putting anything in hdd and messing up my working config.

Edit: I can try beta 4 again if I can figure out how to output LPCM from aac audio track without updating the driver. The driver that dharma beta comes with does not work with aac. I get no voice and probably only two rear channels.

Code:

ERROR: (VDPAU) unable to init VDPAU - vdp_st = 0x17.  Falling back

vdp_st = 0x17 means:

Code:

The system does not have enough resources to complete the requested operation at this time.

We should probably print that string in the log.

I'm having this same problem, having had beta 2 working perfectly and then performing a fresh install of beta 4. I've got the later Revo 3600 which has 2GB of memory though.

Can you advise as to how I would go about downgrading the video driver?

I have stuttering too...came across some specific error messages listed in this post:

http://forum.xbmc.org/showpost.php?p=639520&postcount=1

NOTE: I'm not using a LIVE version...can't say 100% if problem existing in Dharma Beta 1...just another data point...ignore if unrelated. Thanks.

I see nVidia released a driver that supposedly fixes the memory allocation issue just yesterday. I'll give it a try tonight and post back.

Installed the driver but couldn't get X to load at all. After hours of searching I eventually found that the kernel module:
/lib/modules/<kernel-version>/kernel/drivers/video/nvidia.ko
hadn't updated properly. Once I'd renamed the existing module and symlinked the updated one everything worked, BUT...

The problem persists.

Seeing as I'd like to actually watch things tonight, I'm just gonna revert to back to beta 2 or 3. Pity.
