If it doesn't find any channel, configure your antivirus and Windows Firewall to allow the application to communicate. Go to Start, type Firewall and open Windows Firewall. Click the Allow a program through Windows Firewall option and check the box next to Presto! PVR. If you can't find the application in the Allowed programs and features window, press the Allow another program button, navigate to the installation directory, select the executable file and press Add. After that, from the Advanced Settings select Inbound Rules > New Rule. Check the Port box, click Next, select All local Ports and follow the self-explained steps. If it still doesn't work, try uninstalling the application and then installing it again. Alternatively, you can use a similar program from Software Informer database.
