Q 2008-01-22 10:19 AM

Anyone else have any other suggestions? I am still trying to fix this problem. Since the last post I read someone with a similar problem and they stated it may be telecine judder.

I have spent too much time with this and have got nowhere. The picture judders on 1080i source on slow panning shots. It is bothering me more and more.

Latest bios, latest ATI CCC drivers. Have tried PowerDVD 7.3 and have tried every option in the video section possible. Have tried every option within CCC. I have tried all the options within MP10, 11.

I am debating uninstalling all the video codecs and installing one by one to see what happens but that is time consuming.

Any other thoughts?

There will always be some judder on film material being played back on 60Hz display. Even if it were playing at an even multiple of 24Hz you'll still see some if the pan is too fast.

That being said, if you are experiencing a lot of judder you should consider trying out reclock.

Q 2008-01-22 11:24 AM


When I pause the scene on panning at the right time it shows 2 frames which are blurred. A little judder would be acceptable but I think this is worse. Not bad enough that the wife says anything.

That filter does it require Direct Show because I never used it before.

I can't say as I've ever seen that one before.

During moving scenes it's expected to a certain degree of that on an interlaced display but I would have thought that when you are paused you would only be seeing output from a single frame. It may have something to do with the way the integrated graphics work.

Reclock is a Direct Show filter. I'm not sure how well it would work with the S/W you are using but it's pretty straightforward to try.

Remember, create an image of your system before you install anything!

Q 2008-01-22 03:40 PM

Does anyone think getting a HD 2600 pro of XT card will get rid of this problem?

jvincent 2008-01-22 04:13 PM

It's really hard to say without seeing it firsthand.

If you can get a HD2600 from somewhere that will allow you to return it, then it's worth a shot.

Q 2008-01-22 07:57 PM

Here is a pic if it sparks anything for anyone. I am still thinking it is a codec issue but have exhausted everything. Ignore the camera flash. You can clearly see the cards are a double image and blurred. This was a slow panning scene with the camera moving upwards.

jvincent 2008-01-22 07:59 PM

Was it paused when you took the pic?

If you're looking to see if it's codec related, download the TheaterTek trial and see if it's the same. It uses the Nvidia PureVideo decoders, which are quite good.

Q 2008-01-22 08:27 PM

Yes it was paused.

I downloaded the trial of Nvidea purevidedo codec and it seemed the same but I couldn't play with it more because it kept losing the Digital connection (DVI to HDTV). I already used up my theaterTek trial a long time ago.

I wouldn't mind trying again but it won't let me unless anyone knows how to clear it from the registry.

Hey Q!!!

Your earlier post that had this comment finally jarred my brain...

I DO see that kind of thing on my 690G setup but it is not enough to drive me bananas and we get enough 720p content from my Rogers firewire setup that I don't get as many opportunities to see it with 1080i content.

As jvincent said, if you can take the card back if it does no good, go for it. From all of the reviews I have read and all of the testing and comparing that I can do here at home, a discrete video card "should" cure all of those issues and possibly clean up the playback in ways that you were not expecting it to.

I know from my testing of BluRay from the HQV BluRay disc that the 690G fails all of the image tests. The image still looks great but there is modest tearing, poor jaggies compensation and so on.

I commented in another thread that I am about to get a HD 2600 Pro soon (Just because. Yes that is a silly reason. :) ) so I guess it is either you or me to see what benefit can be had from that card in realworld use.

Q 2008-01-22 09:00 PM

Ok so maybe it is not the codec then.

I already ordered the asus module which has a digital coax and optical output. I would just disconnect the current module and connect this new one.

Futureshop has the cards I am looking at buying but they are ATI brand name and almost double the price from the sapphire and gigabyte cards. May be good for testing though.

THanks for all the help guys.

What OS are you using?

I've been on top of MS and ATI for months to correct an issue with 1080i ATSC playback on Vista with the 690g chipset. It manifests as a green screen using the Microsoft MPEG2 decoder, and stuttering playback with other decoders. It's fixed in Vista SP1, which is available for public testing now. This fix is not available via driver updates.

May or may not be related to your issue, since I see the problem with Media Center. But if you're on Vista, it may be worth trying.

Good news on the new low and mid level 3xxx series cards.

Not sure how long you can hold off Q but these sound like some real nice HTPC solutions...

Q 2008-01-23 10:23 AM


I am using XP pro.


I can suffer forever but if there is a $100 solution which there may be right now then I will probably fix it. I want to be sure this works so I will be doing testing first before I actually pull the trigger. New cards are always nice even if it just lowers the cost of existing ones.

Q 2008-01-23 01:18 PM

If I did get a HD2600xt or PRo from Future shop or bestbuy it would be ATI. If I had good results and bought the much cheaper Sapphire or another brand the results should be the same right?
