I ended up ordering a USB-UIRT for IR control.
I installed the Colossus 2 on Friday, but couldn't get it to work with JRiver as either a tuner or capture only. There was no picture or sound. The channels are unencryped and I confirmed that it worked with WinTV 8, the app that comes with it. Any suggestions?
It is in a friend's HTPC, but I can access via TeamViewer. I also just ordered another one directly from Hauppauge.
