SageTV Graphics: 2D engine or 3D engine?

[Underfunded]

OK. I am suffering from stuttering on my HD channels even though my system is plenty fast enough to play them (plays fine through VLC). Before I go and drop another 200 on a new video card when I'm running an ATI x1800xt already I want to try overclocking my video card. ATI sets it up so you can overclock the vid card in 3d apps easily but that will only kick in during a 3d program.

Is SageTV considered a 3d program?

You shouldn't need to buy a new video card. What decoder are you using for playback?

I am using the Nvidia Purevideo Platinum and followed the setup in this thread:

But am still getting studdering issues.

I just ran GraphEdit and here is my pathing:

VIDEO FILE > NVidia Transport Demux > NVidia Video Decoder > Video Renderer
> NVidia Audio Decoder > AC3Filter > Default Direct Sound

In SageTV all the settings are to use the system defaults except the MPEG2 Audio which is set to the SageTV decoder or else I can't seem to get sound out of my SD channels.

Uncheck the "Do not encode stereo PCM" box in AC3Filter to fix that.

Try using the Overlay video renderer in Sage's Advanced Setup. I have an XT1600 Pro, and I don't have stuttering (except occasional). I do though when I use VMR, which you seem to be.

Also, make sure you're capturing HD content to a drive local to the server (i.e., not to a network share).

thank you all for your help. I figured out my problem, partially. I am now watching my HDTV with no stutter.

My big issue I think was that I forgot to disable virus scanning on my tv recording drive.

The other thing I did was download the Cyberlink ATI decoders to utilize my ATI x1800xl video cards hardware instead of the NVidia Purevideo using my CPU.

Thank you all again.
