Watch for Virus Scanner when capturing!

[jeanl]

I'm posting this in case other people run into the same kind of problems.

I was having dropped frames once in a while (for example, a burst of 80 every 10 minutes), while capturing from my DV camera, using WinDV (great app!), even though everything was turned off. Well, not everything, as I found out: Looking at task manager, I saw 3 processes having to do with virus scanning (McShield, VsTskMgr, FrameworkService.exe). I couldn't kill these processes with task manager, so I had to go to windows services to shut the corresponding services down (control panel / administrative tools / services). The services were called "Network Associates ..." and "McAfee framework ..."

After shutting them down the capture went just fine, 0 frames dropped in about 1 hour of capture.

'hope this helps someone...

On access virus scanning (my experience also comes from McAfee) can be the cause of many strange problems - The virus scanner and the application that really wants access to the file obviously "collide" from time to time.

And on the other side I had Mcafee 2004 and never had an issue with dropped frames while running it in the background. I do have a pretty fast system so that could be why...

If you really want to clean out those processes and streamline your machine go here.... http://www.blackviper.com/WinXP/supertweaks.htm I'm down to about 24 on startup.

That's what I did! And that's also how I found out about these services.
I tweaked my startup too, but I'm way above 24(MB I'm assuming), more like 100MB at startup (XP sp2). I'm wondering how you achieved that (but that's a bit OT)...

24 processes not MB. ctrl & alt & delete and look at the processes tab. 24 includes virus scanner and my firewall running.

Hmmmm, I've seen this sometimes, but not always, were all of a sudden I would get like 18-20 dropped frames in a row, but for no apperant reason.

Maybe it was McAfee doing some scan of a file in the background.

I haven't had any problems while capturing. I use AVG free addition, no viruses after 3 years.

I've had problems transferring tapes while McAfee was turned on. My solution was to disable virus scanning and disable my screen saver while transferring tapes.

I agree. The point I was making in my original post was that to disable all of the virus scanning stuff, you sometimes need to turn off services (some processes won't go when you quit the app, and you can't kill them in task manager)...
