It seems like DMC is almost constantly using 100% of my system resources.   I have 1 gig of ram, 72 gig hdd, and intel xenon 2.4 gig processor.  
This occurs even while the only programs open are the bare necessities.  My hdd is about 1/3 full.
Is there something i'm doing wrong, or is there something i can check?
I've been trying to convert some .vob files to .avi
Before this, i was converting the .vob files to .wmv
Any help would be greatly appreciated.
