V3 playback problems?!

Here's the thing:

I have multitrack, final mix projects that were [recently] completed in v1.0b. These projects reside on known-good, non-fragmented drives and played flawlessly and repeatedly in v1.0b.

Now, when I attempt to play some of the larger 24-bit, 44.1kHz projects in v3.0a, I get frequent audio dropouts/playback stuttering as if I'm hitting a DSP/CPU headroom limit. I've checked all plug-in chains to verify nothing crazy, checked to make sure that all files are located on high-speed media drives where they should be, adjusted Vegas PB buffering and MOTU buffering ad naseum...To no avail.

The playback stuttering occurs at predictable locations, so it does seem to be a bandwidth issue somewhere...The HD access LED's are *not* showing excessive activity at these points.

What's strange, of course, is that I played and manipulated these same projects mere weeks ago with NO such problems in v1.0b.

SO...Does v3 use up some DSP headroom that v1 doesn't? Could there be a resource hog new to this version? Is this a common problem?

And most importantly: How do I get to work on these projects that are, all of the sudden, too big for my PC???!!!

Please advise, ASAP.

System:

PIII 733
256 MB CAS2 RAM
Abit BE6-II MB
Maxtor and WD 7200 ATA100 and ATA66 drives
W98SE OS
ATI RagePro 4MB AGP graphics
MOTU 1224 interface

Nothing else has changed...

Please help!

What software are you referring to when you say v1.0b, Vegas Video or Video Factory? Have you been successful in doing this before these recent files? Are you opening project files from v1.0b into VV3.0a or rendered files?

FYI - Vegas is on v3.0c now, it may fix your problem.

Hello HeeHee [Ha!],

I'm opening Vegas Pro v1.0b project files in Vegas Video 3.0a. The project files, media, and computer are known-good in Vegas 1.0b...Now they choke in Vegas Video v3.0a...Vegas Video v3.0a operates flawlessly otherwise. I have tried all the reboots, reinstalls, restages, driver updates, etc.

There seems to be an inexplicable CPU usage difference between the two SF applications performing the same task...I'm looking for verification [i.e. admission] that this might be the case. Best I can tell, I'm ONE track over some limit in v3 that I wasn't exceeding in v1.0b...This is on more than one project on more than one media drive.

I haven't upgraded to v3.0c because of recent reports of instability...v3.0a is stable.

Any info from SF would be appreciated...

Thanks!

Some people have reported that audio-only performance in Vegas 1 was better with certain projects than it is with Vegas 2 or 3. We have been aware of this for quite some time- performance tuning is an ongoing process.
