This is likely caused by the load on your computer (eg. running too many applications, lack of memory). Here are some things you can try:
1. Close all other applications so you are only running VRS on your computer during testing. 2. Run a disk cleanup and defragment your hard drive to free up some space. 3. Try it on a different computer.
If you are in doubt about whether VRS Recording System will do what you want we recommend you try the free download. Seeing the program in front of you often answers most questions
