My specs:Intel E6550 CPU, 2GB,ddr2,XP SP3. 500GB HDD.

I use Virtual dub,X264 encoder,i start with a xvid video from Hypercam 2,a screen recorder,i stuck it in virtual dub,all goes well until it finished processing a video.

When done i close Virtual dub,a minute goes by,then the CPU utilization goes up to 80% on both traces on the Task manager.
This annoying post process CPU hog thing cripples the system for up to 5 minutes.
There is no new process in task manager and nothing seems be loading or starting up when this happens,always and only when i have used Virtual dub,never another time.

I had virtual dub do this to me when i first began using it,i must have done something to the settings in Virtual dub,the CPU hog thing went away,i encoded 40 videos in about 2 months,all Xvid(Hypercam2) to x264 in virtual dub, no problems.

It's getting on my nerves,any suggestions on what might be causing this?

Audio? If disable A/V Interleaving VD writes entire audio length in single block after video?

Before you close VirtualDub, try changing the video codec to (Uncompressed) before you exit. This will drop the video codec immediately and isolate or rule it out as a trigger. I have seen cases where plugins, codecs, or drivers lose control of worker threads.

If that doesn't work, right-click on virtualdub.exe in Task Manager and generate a dump file -- if you post that I can take a look at what might be getting stuck. This will be a pretty big file, though, so you'll need to compress it and use a drop-box file posting service.
