Audio Underrun and/or Access Violation
Using Avid Xpress Pro on a PC, I’ve been getting either one of the error messages above whenever I try to batch digitize a clip that’s longer than four minutes. It’s either one or the other messages, but what I’m doing is essentially the same. Before the error, the composer window first goes black.
I found on another forum that lowering the system cache might solve the underrun problem, but for the life of me I can’t find where to do this except choosing between “Optimize for disk space” or “Optimize for batch speed” in the Batch tab in Capture settings, neither of which has really solved the problem. Also have tried deleting the MC State file, which hasn’t worked either.
My specs:
Intel(R)Pentium(R)5
Dual Core
CPU 2.66 GHz
1.00G RAM
Intel(R)82801GB/GR/GH (ICH7 Family)Serial ATA Storage Controller -27C0Running Windows XP Professional
Radeon X1600 Series video card
Creative Sound Blaster Audigy 2 ZSAvid Express Pro 5.0.3
many thanks,
Ryan

i had a heck of a time with underruns. In my case is was a bus conflict. Meaning it could not keep up with the data stream. I encountered this while trying to install internal sata drives. My problem, seemed to point to the type of sata controller card I was using. I was trying to raid the drives. If you search underruns there should be a ton of info about it. I couldn’t get the machine to capture at all. As soon as I would start in would run a few seconds and stop with the error message. Sorry I could be more specific, I barely understand it all myself. Abandoning raiding the drives solve my problem

my computer did it too after a friend added some drives for me. it was because of the drive bus not being fast enough for avid. i could capture dv 25 footage but not 1:1
