I suppose you have registered BSplayer Pro and opened the capture device.
When your capture device is open, in the right-click menu of BSplayer, the item
"Capture settings" should be available. Click it and the
"Capture configuration" window appears.
There, in the
up-left corner, you can select the
input source (for example: Tuner/Composite/SVideo...). In the up-right corner you can choose the audio input source and format.
At the
bottom of this window you can select the
channel, but first you have to
configure them.
Press the button
"Configuration". Then,
in the new window,
select your country (mine is Italian, but it doesn't work for me, I have to select German), then
select your video standard (ex: PAL-B)
and the input type (ex: Antenna/Cable).
Finally you can add your channels to the list by using the left pane...
Once all the channels are added, you can change the current channel also from the PlayList window of BSplayer!!
And so by pressing the Next/Previous button!!!
Hope this could help you
BYE :D
