Other XVideo-using software works too. You need XFree 4.1.0 or newer for a 3dfx driver that has XVideo support. It does scale, but upwards only. > > > hacked the bt869 driver for > > 720x576 output with overscan and am now more or less happy. > > Well the "more" in "more or less happy" is good. What about the > "less" part? I guess the less is that the bt869 driver and X don't know anything about one another. So you are pretty much stuck in one X resolution without a lot of fiddle to reprogram both. The overscan is good for video playback but a bit of a nuisance if you are trying to use X (though X tends to look pretty bad on the TV anyway) > Does XFree86 support TV-out with the Voodoo3 or was that part of your > hack? The bt869 driver, that is part of lm-sensors, enables the TV output. But X knows nothing about it, so its necessary to manually make sure that the X modeline and the bt869 settings match up. What resolutions does it support without your hack?

The bt869 has two "built in" resolutions - 640x480 and 800x600. Both are "overscan compensated" - which resizes them to make sure that they all fit on the screen. This is a good thing for computer output but wastes screen space for video output. Steve
