Hello,
1) The Linux KERNEL has an API for video devices: Video4Linux. One driver that
implements this API is the bttv driver.
2) XFree offers capabilities for overlay video display via the XVIDEO v4l
bridge. This makes sense due to some technical advantages (better redraw).
3) kdetv is a plugin based program. It can have several video plugins that
support different video display methods:
3.1) The kdetv xv plugin implements video display using the XFree v4l bridge.
The devices are called "video4linux - XVIDEO port XXX"
3.2) The kdetv v4l plugin directly uses the Linux kernel and it's video4linux
kernel API to display video. The devices have the name of your card with the
device postfixed (e.g. "BT878 Video (Hauppauge WinTV PVR)
Video4Linux(/dev/video)")
From your further info below, I see that kdetv does not detect any device.
This usually happens if kdetv cannot load it's video plugins. Go to the
config dialog, page "Video". Look if kdetv found the two video plugins I
described above (xv and v4l). If not, you downloaded the wrong rpms for your
system.
If yes, you have a problem with your bttv installation. Do other programs
work?
BTW, the debug output from the bttv kernel driver looks stange to me, looks
like it finds two video cards but initialises them both as bttv0... Are you
sure you correctly set up your driver?
