FYI, went back to ivtv 0.3.3 driver yesterday and the quality is much better than 0.2 (at least with my card) - no more static around the fringe of the image.
The hard part is finding a version that will work with your card.

| Post subject: | i586 vs. i686 |
When the installer asks you if you want to install i586 or i686 what is the difference exactly? Has the software been optimized for certain processors? I've got a Duron processor, but I installed the i586 just because I thought that would be a safe bet for my first shot at this. If I were to install i686 would I notice any performance boost? Jon |

The difference is how the software is compiled and optimized. It can make a significant difference in performance to use the "new" or "enhanced" instructions, or just to use different sequences based on pipeline behaviour. |

the duron should be able to use the i686, the only thing that many people use that can't is the epia boards. |

Does it effect just MythTV or the whole Linux OS? |

just mythtv. most of the rest of the os is based on debian which is compiled for i386. |

This is interesting... I decided to do a complete reinstall of R5A16 this morning; figured I had messed up the original files enough, and now I have a better idea of how things work. I installed the i686 version of MythTV, the Nvidia 7174 driver script, and the stuck with the original ivtv driver from the R5A16 CD (with a few tweaks for my card). I configured Myth and now my CPU usage is less than 40% when watching Live TV!! This is with an 800Mhz CPU at a pretty high bitrate, BTW. Whoa! I'm not exactly sure where this performance boost is coming from but I'm not complaining... Just to test it some more, I enabled XvMC in the Playback options and CPU usage dropped another 10% but the playback didn't look as good. It didn't lockup when doing ff/rw but it didn't look right and I have decided to turn XvMC off for now. Also, I think the ivtv 0.3 driver gives me a little better picture (there is a static line at the top of the picture with ivtv 0.2) and I may try installing that again but I'm a little worried now that it's working so well. Now it's time to get some Wifi going in this puppy... Jon |

I must agree I had the 3.x drivers installed for a short while, cause I thought I had an issue with the 2.x drivers (turns out I was overlooking something) and it gave me a better picture quality, but I had serious errors with playback very strange errors, though this has been a while back, and development marches on, but 3.x is still the development branch, so big problems like that can occur. |
