Yes... same result :((

Two things to check:
- try temporarily disabling audio component in device manager. If that helps, search for updated audio drivers, disable software 3d features in audio.
- VIA firewire chipset on motherboard could be a culprit

Probably because there is no OpenGL support on the second monitor. Go into Control Panel and make the secondary monitor the primary monitor. Also try upgrading your DirectX drivers.

-Dirk

My second monitor is an external video monitor connected on my camera.
I have indeed a VIA firewire chipset on motherboard, but why playback is jerky with WinXP and not with Win2K ?

BTW,in this post, "dmcmeans" advice to disable firewire network connection :

dont work for me... :(((


Thx

Have the same problem. When upgrade to Win XP Pro I got jerky preview on external monitor through firewire. Hardware of the computer is the same. I try all the advices about it, but nothing helped: IRQ, DMA, defrag, recompress, paging file, newer (older) video drivers, directx9 and other useless stuff.

Capture, print to tape, playback in Windows Media Player are fine.

I noticed one interesting thing. Wnen I paused during playback on the timeline the picture on TV has jitter (even if the footage has a little motion). Doesn't matter what is option of preview: draft, preview, good or best, dock, undock. Why it's happened? I haven't it under Win 2000.

It seems to me that Win XP Pro and VV3(V4) are not "friendly" and the problem is inside Vegas.

P III 800, 512 RAM, 7200 HDD, OHCI 1394.

->It seems to me that Win XP Pro and VV3(V4) are not "friendly" and the problem is inside Vegas.

I agree with you.
Do you know if WinXP-Home & Vegas are more friendly ?
Thx

>Do you know if WinXP-Home & Vegas are more friendly ?

Don't know, but I'm not sure.

I too have this issue with XP Pro on one machine and XP Home on another.

XP Pro vs Xp Home shouldn't matter as both have the same codebase... In fact, XP Pro would be preferable as there's a greater ability to turn services off.

Might want to search the forum for info on common things to turn off in VV4 to allow smooth playback from the preview monitor.

I'd suggest trying to go out to your camera -> monitor using something other then Vegas, or perhaps using print to tape. If it happens all the time, i.e.: outside of Vegas, then the prob would be with XP &/or your firewire output.

Could try dissabling or stopping some of the services in XP... XP has a bit more going on behind the scenes then win2k by default, and one of these services could be periodically pulling resources away from your firewire stream. See http://www.blackviper.com/index.html

Could try using a separate 1394 card (I've seen them for $12).

I tryed Première6 with Xp and i get smoothly playback... so i think the problem is inside Vegas.

Mikkie, if you are using Vegas with XP (with out jerky payback), can you describe your hardware please ?

Thx

Rosebud,

I've read both threads on this problem. In this thread, you state that you have just built a new PC and that the new PC has Win XP-Pro installed. You also state that you had no preview problem using Win 2000. The question arises, is Win 2000 installed on your older PC?

Or, have you tried both Win 2000 and Win XP-Pro on your new PC?

->have you tried both Win 2000 and Win XP-Pro on your new PC?

Yes and i get smoothly playback with Win2K.

I tried WinXp on my hold PC (PIII650) and i get jerky playback too.

Sorry Rosebud,

I've done some research but I lack the level of technical capability needed to help resolve your problem. It sounds as if Win XP and Win 2000 might be assigning interrupts in a different manner - with Win Xp creating a conflict between your graphics card and your Firewire controller. One of the other posters mentioned that he had checked IRQs so this is probably not the answer. So, I'm stumped.

I sure hope that someone solves this problem and posts the results.

JackHughs

I have Windows XP Pro and used both VV 3.0 and V 4.0 and not had any such problems.

Please Jayglad, can you describe your hardware ?
Have you make any setting in WinXP ?
thx

Like you, I built the unit myself. Basically, it consists of an Asus A7V333 motherboard, AMD Athlon XP 1800 CPU, 512MB PC2700 DDR 333Mhz memory, ATI Radeon 8500 128MB DDR video card, one WD 20GB 7200 hard drive, and two WD 1200JB 8MB-cache 7200 hard drives.

I just put it together, loaded the OS (no adjustments were made) then the software and it's worked just fine since June of last year. I don't use this computer for anything else but editing video. That may or may not have anything to do with your problem.

Well... SoFo can you tell us what you think about this problem please ?
Thx

please post your irq layout here- that often points to problem areas.

http://perso.wanadoo.fr/g-prod/irq.gif

I achived the config when all of the hardware's elements has it's own unique IRQ.
But nothing, still I have jerky preview.

Does anybody solved the problem after IRQ's changing?
Please, answer.

I have the same pb than Rosebud:

Intel PIV 2.55
Mobo Asus P4B533
512Mo DDR Ram
20 / 1000 / 120 Go HD
Hercules DV Action
Matrox G450
WinXP Pro
Vegas 4
Sony VX2000

IRQs:

Meanwhile, the playback is fluid with Adobe Premiere
Thanks for help.
