It can be quiet a pain trouble-shooting that problem. Reinstalling the PCTV drivers along with the vision may solve it if you are lucky. I have a PCTV Stereo along with a 9800 pro display card, sometimes when i used to fiddle with the catalyst and omega drivers, the same problem arose out of no where. Do give a try to Chris Tv, it quite feature rich, light on resources mebbe a lil buggy for the starters but works like a charm if you get it to work. Can be configured heavily and a must try. Get it from
here It has files which can make the Pinnacle Remote to work, i havent used it personally, but i am sure it would work.
