User manual HAUPPAUGE WINTV-HVR-1250 MC FOR VISTA MEDIA CENTER

[. . . ] Note: ATSC digital TV is NOT digital cable TV or digital satellite TV. Currently Vista Media Center cannot display digital cable TV or digital satellite TV. ATSC digital TV is transmitted in several resolutions, from "standard definition" which is similar to cable TV, up to high definition which has about 16 times the resolution of normal cable TV. In any resolution, ATSC digital TV gives sharper pictures than analog cable TV and near CD quality sound. [. . . ] To install the Media Center remote control receiver/blaster, simply plug one end of the supplied USB cable into the Media Center remote control receiver/blaster box and the other end into any USB port on your Vista Home Premium or Ultimate PC. Media Troubleshooting . Some notes on system compatibility Decoding high definition HD TV is very CPU intensive. A graphics card with at least 64MBytes of memory and the latest graphics driver from the manufacturer makes the decoding task easier. Typically a 2. 2 GHz Pentium 4 processor or equivalent with a graphics card having 64MBytes of memory is required to properly decode ATSC digital TV on your PC. A 1. 6GHz AMD Sempro computer tested in the Hauppauge lab used 50% of the CPU for playing ATSC 640i format, and 90% of the CPU when playing ATSC 1080i, the highest definition ATSC format. In some cases, either a faster processor or more graphics memory might be required. Slow or jerky video and a noisy TV picture indicate system performance problems. Jerky video with live ATSC digital TV Jerky or distorted video can be caused by two things in your PC or laptop: a slow CPU which cannot decode the ATSC TV signal fast enough, and a graphics system which cannot keep up with the high datarates of ATSC TV. Center will automatically load the drivers for the MCE remote control. To test the receiver, click the Start button in the middle of the remote control. If you have a satellite set top box and would like the Media Center remote control receiver/blaster to change channels on the set top box, plug one end of the IR transmitter cable into the back of the Media Center remote control receiver/blaster box and position the other end (the transmitter end) over the IR receiver on your set top box. Then run the TV Tuner Set up under Media Center (see below). Many times, improving the performance of the graphics display will fix the jerky video display of ATSC digital TV. Here are some tips on improving graphics performance: - Use the latest graphics driver: graphics drivers are often `tweaked' to improve performance, especially the built-in graphics on laptops. Check the Microsoft Windows update site to download the latest graphics driver for your computer. For Dell computers, check the Dell website for the latest graphics driver. - Use Hauppauge's Primary program to optimize graphics performance: Primary. exe is used to change the display mode of a graphics card for TV watching. This does not affect any other Windows program. Primary. exe is found in the Hauppauge WinTV program group. The default mode used by WinTV is Force Primary. Force Primary uses your processor to move the digital TV image into the graphics memory. It is more CPU intensive but often fixes display problems on some laptops. To use hardware graphics acceleration, close your TV application, then run Primary. Close Primary and rerun your TV application. [. . . ] When it is finished, it will tell you whether you have a cable TV, antenna or set top box connection. After determining the type of signal, you will see You are Done!Now you need to set up the Electronic Program Guide. You will see a message: Set Up Your Program Guide. [. . . ]
