settings & decoder for ATI 4670 card

[xj-boonie]

Using WinXP and an ATI 4670, what settings should I have, and what decoder?

Basically, what settings for:
Video Renderer
MPEG2 Video Decoder Filter
MPEG4 Playback

I currently have:
VMR9
NVIDIA Vedio Decoder
SageTV Player

Was using a Nvidia 7600GT and have installed Nvidia Purevideo.

Thanks,
Mike

Nvidia Purevideo will not use the ATI AVIVO hardware acceleration. I have had issues with drivers with the ASUS 4670 512MB but have solved by installing on a fresh OS using Cat 8.10 only (do not install earlier Cat (ie 8.9) or the shipped drivers).

As for your question, you should use a decoder that can take advantage of your video cards DXVA (hardware acceleration) capabilities. Example decoders are: ArcSoft, Cyberlink, CoreAVC. These can be purchased by buying the video player software associated with them. Example Cyberlink video decoder comes with Cyberlink PowerDVD Deluxe/Ultra.

There are a number of other tweaks that you can find in other posts for fixing tearing, video stuttering and softness of video if you encounter them.

Hope this helps.

I have a ATI 3450 and there seem to be a limited number of codecs that use the cards hardware at this point. The Nvidia cards seems to have more support right now.

I use the AVIVO codec that came with the card. After you install it should show up as an option in Sage. If you downloaded the latest driver from the ATI website than you don't have it. It is a separate install. The only other codec I have that seems to use the hardware on the card is the Cyberlink 7 that came with my BluRay drive.

H.264 content from HD-PVR and BluRay looks best with the ArcSoft codec that came with the HD-PVR but it has like a 50-60% CPU usage. (Same with the CoreAVC codec) I am currently using the Cyberlink 7 for h.264 and the CPU during playback is like 2-4%. The Cyberlink does not seem to look quite as good as the others but it still looks good.

I would be interested in testing the Cyberlink 8 codec but it does not seem to have a trial. I wonder if it would be worth the upgrade. It also seems that ATI would have a H.264 codec but I have never found stumbled across anything.

If you go to ati's driver download page, click on optional download link "Individual driver download packages, ATI Multimedia Center, Avivo, and Korean full package" and find the link to "Complete Avivo Suite for X1000 series products or higher." The complete Avivo package will install an ATI decoder that's essentially the ATI version of the Cyberlink decoder, which you can use in Sagetv.

Did this and Sage seems to be using the decoder (the nvidia icon doesn't show up in the task bar any more), but the picture still looks a little off (when compared to the TV's tuner) - like it's ghosting or something. Where can I tweak it?

Thanks,
