I'm also having this same issue. What's strange is I got everything working for a few days, then I played around with MCE, SageTV, and running under a non administrator account and somewhere along the line it stopped working and has the same symptoms.

The Hauppauge IR Blaster config is setup the exact same as when it was working and allows me to change channels using it's setup utility. However, in BTV, the IR will blink but nothing will actually happen.

I tried uninstalling all Hauppauge software and drivers and then reinstalled them but that didn't work. I tried deleting and readding the source in BTV, and I've tried uninstalling and reinstalling BTV, no joy.

I'm runing Vista Ultimate (32bit).

If anyone has any breakthroughs with this do share!

Edit: I'm running the latest Hauppauge drivers and BTV 4.6.1
