AVS tvbox.

Hi pal I wonder is it actually free this AVS tvbox, yes beside the naging pop-up the program seem to have a problem with my computer. When I run this program windows pop-up a message " AVS TV Box has encountered a problem and needs to close. We are sorry for the inconvenience. Bla ..........". The funny part of it is when you remove the 'video in plug' from the USB video capture device before you start the program then all will be fine. My OS. XP Pro SP2. P4. using USB D-Link videp capture device. Can anyone please help me to solve it. Thanks.
