Last week I recieved a new Dell Studio Slim 540s Desktop factory equipped with a Hauppauge 1250 TV tuner. The computer is running Vista SP1 Ultimate 64 bit operating system. I went through the set up instructions and found that the Live TV video and audio being feed to my 47" LCD screen TV by Windows Media Center was choppy. BlueRay disc, DVD and music file playback are all fine. I uninstalled the ATI Radeon HD 3450 video card and connected the HDMI cable directly to the HDMI cable outlet on the motherboard and I still had choppy video and audio. While the video card was uninstalled I attached a 20' flat panel LCD monitor to the motherboards VGA port using the monitors VGA cable and still had the problem. Only Live TV through Windows Media Center is problematic. I have spent 3 hours online with Dell tech support and after they had tried all they could think to try they suggested I reset the computer operating perameters to the factory settings and told me they would call within 48 hours to ensure the problem was fixed. I did as they suggested and the problem was not fixed. After 72 hours and no call from Dell I called Dell tech support and spent another 2 hours without any positive results. The call resulted in the Dell support technition sugesting that I have my local cable system operator check the cable signal and connections. I had the local cable operator send out a couple of technitions to check the signal going to my system and they found no issues. They did notice that the static that was displayed on the monitor when the cable was disconnected from the tv tuner still appeared to be choppy. My TV works great with the cable connected direct. I have replaced the TV tuner with a new tuner exactly like the tuner that was installed from the factory, remember this is a new computer, and still had choppy video and audio. As you can tell I have systematically eliminated the systems additional components as the source of the problem. I am now left with 2 options; 1) The Vista operating system is the problem or 2) The processor is the problem. Maybe there is something I am overlooking. I am open to any suggestions.
