-      <LI><B>MPEG4:</B> 640x480@32=1228800<BR>
-        You need a video bandwidth of 1.2*25fps=30MB/sec. To watch such a movie
-        in real-time you need a PC equivalent to a Celeron-450 and a DIMM based

-        You need a video bandwidth of 3*30fps=90MB/sec. In extreme cases (if your
-        video card supports IDCT decoding) the hardware requirements are the same
-        as for MPEG4.</LI>
-      <LI><B>HDTV (High Definition TeleVision):</B> 2000x2000@32=16000000<BR>
-        You need a video bandwidth of 16*30fps=480MB/sec. You also need at least
-        32MB of video memory to watch this stream: 16MB for the RGB area and 16MB
-        for the YUV area.</LI>
-    </UL>
-  </LI>
-  <LI>The bandwidth of PCI slots is: 33MHz*32Bit=133MB/sec. PCI2.1 has
-    66MHz*32Bit=266MB/sec which is more than enough for playing any movie (except
-    HDTV streams which really require an AGP bus).</LI>
-  <LI>What memory type should be installed on the video card:
-    <UL>
-      <LI><B>SIMM</B> - Avoid that.</LI>
-      <LI><B>DIMM</B> - Good if your video card has 128-bit memory access.</LI>
-      <LI><B>DDR</B> - Is fast enough for all types.</LI>

-</OL>
-Note: DGA comparison shows that there is no visible difference between video
-cards which have the same type of video memory installed.<BR>
-<B>Conclusion:</B> If you have enough CPU power (Celeron-450 or K6-2-500) it
-should be enough to buy any video card which has at least 8MB of DIMM or DDR
