VIA chipset problems?

Last week I was running Vegas 3.0c on a 700mhz Celeron with 320mb memory and getting virtually perfect playback from the timeline to an external monitor through a Sony converter. Over the weekend I went to a new motherboard, chip and memory and added a DVD burner-- all other hardware is the same. Now I have a 1.4 AMD on a Shuttle board (kt266 VIA chipset, 512mb) and the external playback skips or stutters annoyingly. It does this with or without the vlatency patch installed and has defied all tweaking.

I've noticed a number of AMD owners complaining of playback problems on the forums, and it never seems to get resolved. Does Vegas Video have some issues with the VIA chipset?

DL the latest 4-in-1 drivers from viaarena.com

Is this the KT266A or just the KT266?

Never an issue here with any SoFo apps using the KT266A w/latest drivers.

No problem here using Vegas 3.0c, AMD XP 2000+ and and Asus A7V333 (with Via KT 333 chipset). Everything works great.

Have seen Vegas run flawlessly on 3 different MB's running the KT266A chipset, ( be sure to install the latest driver package). Dont know about the Shuttle board. You might check out overclockers.com, go to their Forum section, and check out the amd motherboard section, then look for problems ans/or fixes people might be having with that particular board. Overclocking isn't video editing, but there's lots of discussion about particularbproblems any board might have..

Thanks everyone for the advice.

It is the kt266a and I'm already running the latest drivers.

What Firewire card are U using? what is the driver installed under device manager for that hardware?

Been there ...
I had to get my firewire card onto another IRQ.
There must of been a conflict, even though it did not show up as a problem
in device manager

Shaunn: Thanks for the suggestion, but I don't think the card itself (Maxtor, same as my external drive) is a problem as it worked perfectly before and uses Microsoft native drivers.

vx2000b: IRQ problem seems most likely, though the card sits by itself on IRQ 5. Radeon 7200 is on 11 and soundcard shares 10 with USB controller. But when I was running on the Celeron chip I was able to move the card to different IRQ's to experiment, but don't seem to be able to do that anymore since installing the AMD.

Perhaps it's an issue between VIA and Windows ME? In fact, I've kind of lost IRQ 9 since the upgrade. Windows says it is available but it does not show up at all in resources. I can't route anything onto IRQ 7 either, though it just has the parallel port on it and no hardware is connected to that. I think a change to Win2000 is probably called for, but I'm in the middle of a project and can't reformat for a while.

Here's a weird clue, maybe...Last night I thought I'd try running some silent footage, to see if perhaps somehow audio was influencing the stutter problem. I opened an new project and dropped a silent clip directly onto the timeline from the explorer window. It played perfectly the first time, then everytime after that it was full of stutters. I exited Vegas without saving, opened a new instance of Vegas from the desktop, dropped the same clip onto the timeline and got the same pattern: it played fine the first time and stuttered everytime after that. Pretty strange, huh?

There is no stutter problem in the preview window within Vegas even in best quality, only on the external monitor. Print to tape is fine also, so I'm not out of business or anything. It's just disappointing to upgrade the computer and not see the expected upgrade in performance.

Thanks to all,
Finster

Hang in there, and looks like you should be able to get thru your project OK.
Since your hardware changed, might not be a bad idea to do a "reapair/upgrade" install of your OS....less you already did that.
Is the video stored on the external drive? Shouldn't be an issue, but there have been stories.
Yes, when project is done...I recommend Win XP or 2K...FRESH install after repartitioning etc.
I too am using the AMD 1.4...same chipset...also using external drive(had issues at one time with audio op time out...Gone now).

Have you set up the bios? Sorry for asking, but you didn't mention. It may still be at "fail safe defaults".
