You will need a channel changer (ir type). usb-uirt is one reliable. The pvr-150 comes with one (not the mce version), but that one only supports boxes that hauppauge has support for. You will have to check with them if they support coolsat.
On the other hand, you can use gbpvr as a vcr, and just schedule the times as on a normal vcr. It just defeats the purpose a bit
