[snip Cory's excellent in-depth explanation] In case Cory's response left you scratching your head a little bit, here's the bottom line: - not all BT878 cards can capture audio over the PCI bus (btaudio); some still require a pass-through to a sound card for recording audio. Determining if a particular card supports capture via btaudio before you buy it is somewhat of a black art, because manufacturers are constantly revising their cards, changing chips/chipsets, etc, but not changing model numbers. - some BT878 cards do stereo; notably the WinTV-dbx models. I happen to have one (WinTV-radio) that does both dbx stereo *and* btaudio, so I can capture stereo audio right over the PCI bus. Again, there's no guarantee that a *new* WinTV-radio card will support btaudio, because of possible revisions to the card. -JAC _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
