You can receive a single transponder...no matter how many channels. However
vls currently supports only serving a single channel per card as far as I

If transponder mean satellite then I see that for instance
<http://www.loralskynet.com/> Telstar 5 at 97.0°W have 80 free channels

http://www.lyngsat.com/t5.shtml <http://www.lyngsat.com/t5.shtml>  or I
wrong. Can one DVB card recieve 80 channels?

Could I config it on video card (if yes How?) or on VLS (How?)?
