MythTV uses a linear blend algorithm for deinterlacing, which will improve how the image looks on your screen.  Deinterlacing requires that your processor support SSE. (Streaming SIMD Extensions, aka "MMX2"). Early Intel Celeron (those that don't use the Coppermine 0.18um core and are usually <600MHz), Pentium Pro and Pentium II CPUs do not have SSE, so make sure you haven't enabled deinterlacing if your processor doesn't support it. If you enable it, and your processor doesn't support SSE, you will get "Illegal Instruction" errors.</del></div></td><td colspan="2"> </td></tr>

Any processing will modify the original image so you should assess if the filter has made a noticeable improvement to the picture in order to justify the impact of the processing. Adding any filter will inherently increase CPU usage. The impact can vary dramatically depending on your CPU type and speed, the resolution of the recording, which filters you are using and other factors. You can only determine what is right for you through experimentation. However, as a starting point, here are some filter strings that you may find useful:</del></div></td><td colspan="2"> </td></tr>

However, it is highly recommended that you use a card which supports XVideo (XV) extensions. If your card does not support XV, color conversion and scaling will be performed by your CPU rather than the video card. This is very CPU and memory intensive and will often result in dropped frames and a corresponding degradation of quality. Check the X documentation for details if you are uncertain about your preferred card. You may also run xvinfo; look for your video card to be listed as one of the adapters.</div></td><td class='diff-marker'> </td><td style="background-color: #f9f9f9; color: #333333; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #e6e6e6; vertical-align: top; white-space: pre-wrap;"><div>MythTV will work with just about any video card.
