It only seems to be an issue with rips of that size and BluRay bitrate. I'm having occasional stutters and dropped video frames as shown in the log I've attached. I've disabled the vdpaubuffersize=48 and vdpaustudiocolor from my VDPAU Playback Profile (Advanced 2x). I don't seem to be having issues with any of my 1080i MPEG2 recordings from OTA TV. I've also enabled "Extra Audio Buffering" and disabled "Real-Time Priority". Once I did that, I thought all was solved. It was well over an hour before I saw those errors again. Compositing has been disabled via xorg.conf and I've even set the nVidia PowerMizer to Performance Mode. I had to do that with a separate script that runs after Xorg loads. I added to AUTOSTART in MythBuntu. I've verified that PowerMizer is set to 1 after a reboot.</div>

<div><br></div><div>Is your video card plugged into a full x16 slot, I know some motherboards have slots that look like x16 but are really only x4. I doubt it's the issue but perhaps Blueray needs that extra bandwidth.</div>

My question: Is my setup just too slow to handle the BluRay bitrate I'm trying to put through my machine? Is it time for me to build a new front end machine? Or is there something else I'm missing? Should I ditch the GT430 and get a 520? Any help would be appreciated. Thanks!</div>

The GT430 should handle all of the heavy lifting so long as you get the content to it fast enough.</div>
</div></blockquote><div><br></div></div></div><div>Thanks for the reply. My network consists of an HP ProCurve 1800-24G 24 port Gig switch. I have a single cable running up to a Dell PowerConnect 16 port Gig switch behind my home theater. It feeds the MythBox, TV, PS3, and Denon receiver. So I've got plenty of network bandwidth. The MythBackend is actually a VM that sits on a hefty SuperMicro motherboard. The storage for the recordings/videos is on a FreeNAS VM running ZFS RAIDZ2 served out over NFS. It's all done over emulated Intel 1Gb NICs (as FreeNAS doesn't have VMXNET3 support).</div>
<div><br></div><div>I'll have to check the port that the video card is in. I'm pretty sure it's a 16x, but Dell could be lying to me.</div></div>
