Actually the tuner is a seperate component, but whatever. =) The 879s do have extra support for FM tuners if your tuner provides the feature. Basically the bttv chipsets handle sound and NTSC/PAL video signals. What is supported and how varies by implementation and the exact chipset used. Example, I've never seen an 848 card which supported seperate chroma/luma inputs (S-Video), so I am not sure that the bt848 does have seperate inputs. Of course, you could still composite the two signals with a few cents worth of isolating components, but it's not true S-Video in that case. Any card with an S-Video port has had a later chipset which I know has seperate chroma and luma pins. > I'd read that Hauppauge's PVR cards, which do mpeg-2 encoding in hardware, > had some limitation, possibly that they *only* output the mpeg2 stream, as > opposed to writing the video itself through the pci bus.

If the HDTV card is a bttv-class chipset, color me interested. We even have MacOS X support for those things (though it's a bit beta-quality at the moment..) _______________________________________________ EuG-LUG mailing list [EMAIL PROTECTED] http://mailman.efn.org/cgi-bin/listinfo/eug-lug
