Not much activity here since AutumnWave and OnAir closed up shop. Some diehards probably check occasionally as I do. But you might have better luck on the Orb forums
. I know nothing about Orb but gave their pages a quick look and found the OnAir GT discussed here
. Note the last posting, by gumby42. It sounds like he had it working until he moved the GT to a system running Win7/64 and installed the beta driver, which may be required for that OS. I know the beta lacks some features found in earlier versions, such as the ability to work with TSReader. Maybe it also breaks compatibility with Orb.
On the Orb site, under Known Issues
, I found this:
QAM digital TV channels not supported - QAM tuners are not supported in orb at this time and, therefore, digital cable channels and QAM-based HD programming cannot be streamed in Orb without going though a set-top box.
So it won't work with digital channels from cable, just from antenna.
I think your best bet is to set up a 32-bit computer running WinXP as your streaming source. But I'm just guessing. Ryan Pertusio might have more insight if he still follows this thread. Or you could PM him (rpertusio). He's certainly the most knowledgeable here about the GT's capabilities, limitations and compatibilities.
