I've been using this player for quite a while, without any problems, but recently that has changed. When I start the program it downloads the channel list, but doesn't see any signals from either the channels or TVU itself. I reinstalled it but the problem remained. It was working properly with the Flash Player update that I have installed, so the only thing I could think of is that something is blocking the signals, like my firewall (Comodo), but TVU is listed on the trusted files and shutting down the firewall doesn't cure the problem. The player I'm using is the latest version, so is there anything else that anyone can think of to fix the problem?
