NTSC DV Playback poor

Greetings all....

Although this is a Vegas forum, not a Window's forum, I'll post my problem here in hopes that someone has had a similar problem and has suggestions.

I am a VV 2.0 user, and have just started using a new system - Dual P3 1000 Mhz on Asus board, 512 Ram, Win 2k Pro, Matrox G550 Graphics, etc.

SO far, things seem to be going fairly smoothly, all except for playback of NTSC DV avi files, within and outside of Vegas. Very choppy rendering. Almost 50% reduction in playback. More compressed files play fine - ie Quicktime Sorensen.

I've update DirectX to 8.1

I'm not sure where to look for the problem. Any suggestions? This is, of course, very disheartening - building a new system that supposed to improve productivity and it lags more than the old one did!

Any help with be GREATLY appreciated.

Thanks.

Update Via, DMA on for IDE drives, defrag, don't share IRQs. Cover all these and your system should fly.

search this forum, for details on each...

Thanks for the advice. Does it stand to reason that my drives (both UDMA1000 7600 RPM) are running PIO even though "DMA if available" is selected - considering that I haven't updated the VIA drivers?

Installing the 4in1 driver won't overwrite drivers for specific hardware - ie my Matrox drivers, or Soundblaster drivers?

Oops - that should have read "UDMA 100". If only we were running at 1000! ;)

When you install new drivers, the installation should not over ride other drivers from components that dont have anything todo.

Try to update to VV3 since the DV in it can actually use the DUAL PROCESSOR as version 2 does not.

I'll add my 2 cents here because I have the exact same problem. The DVD NTSC files do not play accurately in Windows media player or VV3...even with directX8.1, DMA, etc, I get choppy playback and extremely out of sync audio. The files, however, play perfectly in programs better engineered to play back MPEG2 files. I use Intervideo WinDVD (free trial download). This is a great program because it will play back mpeg2 files in DVD or SVCD format!

Well, my problem was 100% DMA related. I couldn't get my drives running at UDMA 100 until I downloaded and installed the VIA Bus Master PCI IDE Utility which allows me to configure my drives to the proper speeds. Strange that I had to go through that to get them running at their optimum speed.

Not really strange. I mentioned the Bus Master fix several times in the past year. Originally I could not get my CD burner to function correctly until I updated the bus mastering and I had just build a new system and the included drivers on the motherboard CD were already outdated. Fairly typical. You did also use a 80 wire cable for your drive too, right? You need to do both and of course have a motherboard and BIOS that supports the high speed drives. Once you got eveything set your hard drive should really fly along.
