Note that, excepting the Tuner 0/1 issue which I just don't understand (since there are only two tuners, not four), there are physical headers on the cart to allow you to have additional switched inputs (more than what's available on the backplane of the card slot). Yes, only one input can be pulled from at a time, but it's a nice feature to be able to switch inputs. Hauppauge sells an accessory cable for this. > Thanks to Brendan Hoar for his modules.conf aliases, I got it working and > successfully used record-v4l2.pl to record 2 different channels at the same > time. :) You're welcome. It's all from reading the knoppmyth forums and the ivtv list. -brendan ------------------------------------------------------- This SF.Net email is sponsored by Oracle Space Sweepstakes Want to be the first software developer in space?
