Hi.
Thanks for the info, which clarified things a lot.
Aditionally, I've seen that the first module loaded attaches to /dev/video0,
the second to /dev/video1, etc. So loading first 'bttv' and second 'c-qcam',
'xawtv -c /dev/video0' will use the TV card, and 'xawtv -c /dev/video1' will
use the QuickCam. Both can be at the screen at the same time.
However, I yet see some lack of flexibility. 'kwintv' is not so flexible.
With the QuickCam video is seen at 320x240, and I haven't seen how to change
it, since video is very slow (on a PII350 overclocked to 3.5x112, with S3
Savage).

Wibello,
I have a similar setup here: Bt878 TV-tuner and USB Webcam. Both need a video device. The USB webcam is activated by loading the "ov511" module. By default, insmod ov511 will try to use /dev/video. On the other side, you can specify a video device to use with XawTV with the "-c" flag: xawtv -c /dev/videoX
So I "symlinked" /dev/video to /dev/video1. The webcam always uses /dev/video --> /dev/video1, which is a valid video device, and I created an alias for xawtv=xawtv -c /dev/video0.
lrwxrwxrwx 1 root root 6 Aug 11 2000 video -> video1 crw-rw-rw- 1 root root 81, 0 Aug 8 2000 video0 crw-rw-rw- 1 root root 81, 1 Aug 8 2000 video1
This way, both pieces of hardware have their own video device, and they both can be used at the same time, without any problem. I don't have to choose a video device each and every time I want to use them...
Hope this helps...
