Program info

I have ProgDVB installed on two computers and use it for my IPTV-subscription. As I change channel, the info for that channel is displayd for a few seconds and on one computer it also displays the time and name for the following two programs on the right hand side, but on the other computer it only displays the info for the channel, not the following two programs. It looks like I have the same configuration on both computers but somewhere there must be a difference that causes it. Any hint would be appreciated.
