The fact that it will export to tape seems to point to the combination of processor and display rather than disk drive or 1394 interface. Try changing the amount of memory the video uses in the bios. Try setting at 128. I just put together a cheap PC just for the internet and it has on board video. At 32M it had limited color and was also slow. I have now set to 128 and all is fine.

I have faced similar problem and did three different thing

1. I used another drive to test if the same jittre things takes places while recording/plaback of the same footage. And found out that yes the same is happening, ie the drive is ok and i just changed the SATA or IDE drive data cable and it started working fine. It so happened when using such cables in coputer we unknowingly fold or tweak them to fit in the box & thereby we break some pin or wire or something which causes the problem.

2. I changed the PCI based firewire cards from all slots to check if it is conflicting with the recording/playback. It worked when it was a problem cox of the sme. I faced this problem only once and since then i kept the Card on the slot bets suited.

3. AND YES main culprit once was the Hard thing it self ... it had ba sectors & I got it change from teh Seagate Warranty.

Try any of the three tests & you will know what is wrong 50:50 chances that you surel will be able to solve the problem.

As it did !

let us all know what was the result.

Thanks Ron,
I will check again the video memory.

and thanks Bankim Jain.
1. I have tried with 2 other drives - no luck. haven't checked the cables yet.
2. Have moved the FW card to other slots - no luck.
3. As far as I know the drives are ok.

Anyway, the minute I solve the problem I will lt you know.

Thanks a lot.

Hi Dan,

My be you should try changing the cables now... that the max I could think off in the abscence of any hardware knowldge from my end !

listen here is your problem in a nutshell
first open your box and check for a agp or pci express slot:
if one is there then do the following
go to local store or online Ie: newegg or tigerdirect
buy an nvidia card 64-256mb graphics card
install it go online download latest drivers for it
and that should solve your problem.

you see your problem is the onboard video is sucking up system resources
and your card may not be able to handle the avi files during playback because
it was not designed to do any decoding.

What OS are you using? and are you using DX9?I have seen this problem with media player and caused by mismatch of Direct x

Dan Plonsker April 23rd, 2005 02:00 AM

Thanks Felix, Yes, I plan on checking with a different video card.
Thanks Jack, I'm using XP SP1 and DX9.0c

Jack Smith April 23rd, 2005 11:42 AM

Sounds like Felix maybe right.You could try knocking down the display from 32bit(if it is set at 32) to 16 or 24 and retest

Dan Plonsker April 24th, 2005 02:00 AM

I've tried changing the display to 16bit before, but with no luck.
Thanks

OK, I'm back. hopefully you're still here....
 
So I've put in a new graphic card - NVIDIA Geforce 6600 with 256MB.
The problem remains...
When playing dv files (captured in premiere, winDV etc.) the image stutter.
I've tried to lower the acceleration while playing it on WMP. It helps but than I get interlaced lines on the image.
If I export the project to DVD or Video it works ok on the TV screen.
More ideas (accept wrapping the computer and throwing it to the sea...?)
Thanks

Felix Valeri August 22nd, 2005 08:03 AM

question: are you capturing and editing on the same drive?
2: if you have two drives, did you set the scratch disk in premiere to the second drive? this also could be the problem:

Dan Plonsker August 22nd, 2005 09:35 AM

Thanks Felix,
Yes. I have Premiere on one disk and the video on the second.
any captured DV files in any program stutter.
I'm looking now into the acceleration feature in XP. I think there may be the problem.
