Haveing problem with Jerky video w/ Nvidia 7600GT

[dman777]

Here's my system:

Nforce 7600GT card
2 gig hrtz dual core Opteron
1 gig OCZ ram
2 Seagate 7200.10 HD's
Windows XP/Sp2

My problem is that when watching DVDs off of my hard drive thru the TV out(regular TV with composite cable) the videos aren't smooth but instead have a jerky motion. This problem is especially worse on older movie DVD's that are Full Screen 1.33:1. The software I am useing is Media Classic Player and ZoomPlayer Pro. I am also useing Reclock but it doesn't seem to help. I am also useing Dscaler mpeg 2 decoder for the decoder. For the Nvidia Driver, I am stuck useing 84.xx because all the 9x.xx's have a DVD ratio bug which stretches the pic.

Does anyone know what can be causeing this Jerky motion problem and how I can get rid of it? Is problem in the Nvidia driver or the VGA card itself?

I would just have to guess. Make sure your video card drivers are correct and up to date.

I use Zoom and MPC at times with never any playback problems with DVDs or any type of videos.

You might try VLC and if it plays them back correctly, you likely have a codec problem. I would think that is a better possibility than driver issues. Even the default Windows video drivers should work with a DVD as long as you have a MPEG-2 codec installed.

If VLC works, uninstall any MPEG-2 codecs and put a different one in there. Installing the trial version of Power DVD, then uninstalling it should leave you a MPEG-2 codec. Or install Stinkys MPEG2 Codec.

If it only happens with MPEG-2 video, then the codec is suspect. If it happens with other formats, then you may have something running in the background, stealing CPU cycles.

yeah, it's a driver issue. i updated the driver to the most recent one and it cut down on the jerkyness alot. although it is still noticeable in films that aren't 3:2....not nearly as bad as before though. i can't stay with the new driver though because it has a bug where it doesn't display the dvd ratio correctly.

Is the jerkyness called Cadences? The reason why I was asking is because it is most noticeable on films that aren't 3:2 and I read in a review that ATI scored really high in Cadences tests for films in all ratios and Nvidia only did good with 3:2 and bad in the rest. So I was wondering if that means ATI's Avivo has less jerkyness in it's movies?

Do you run with split output ? That is, do you have the output going to both the TV and a monitor at the same time ? I have seen this cause jerkiness, and have seen the jerkiness disappear when the output is soley directed to only one device.

Let me restate the problem....it's not actually a jerky motion....it's where if people move they leave tracers. This problem doesn't seem to exist on newer DVD movies, but on older DVD movies this is a real problem. The problem is also exists on Zoomplayer pro and Media Player Classic when viewing on my Computer Monitor, not just the TV out. Could this be a problem of the Decoder(I am useing Dscaler Mpeg2 Decoder)?

Nevermind...got it fixed. It was the Dscaler Mpeg2 decoder. I started useing the Nvidia Pure Video decoder and it fixed the problem.

Hi. I know what you mean by that ,I had the same problem as this with the same card, it wasn't jerkiness, it was more like it was deinterlacing it wrong, at certain times.However the NVIDIA Pure Video codec was the one that seemed to be at fault.After I installed Power DVD 7 and uninstalled Pure Video it corrected itself.However now my problem is audio related.I liked the 'night' mode within Pure Video when using a basic line out and was wondering if there was a way to use the Nvidia audio, with Powerdvd video codec. If anyone could help me with this it would be a great help.Thanks
