I really can't recommend it either, but I haven't seen the issues you're experiencing.

I have the HDMI input on the GTV hooked up to a Windows Media Center PC with Intel HD 3000 video. 9 out of 10 times, turning the TV on works just fine. The HDMI handshaking between the HTPC, GTV, AV receiver, and TV works. But, sometimes something doesn't go right and no amount of pulling cables, rebooting the GTV, receiver, or TV will produce a picture. I have to reboot the HTPC through VNC.

This is a pain in the ass that I imagine wouldn't happen if I was using a traditional cable box. Other than that, GTV is cool to have but I still don't think anyone really needs it. A much cheaper Roku box has more to offer at this time.
