I recently installed Orb 2.51.0032 on my Windows 7 Ultimate machine to use with my Hauppauge 1600. I configured the analog tuner to work in Media Center through my cable STB, and everything works as expected there. When I configure it to work with Orb, I am able to stream live TV, but I cannot change the channels on the STB. Is there any extra setup that I need to do to get this to work?

To change Live TV channels in Orb, you need an USB Infra-Red (IR) Blaster such as the ones included in Microsoft MCE-compatible Remote Control devices.

Make sure to configure your IR Blaster with MCE and then re-run the TV setup in Orb via control Panel. (Click Orb tray icon -> Control Panel -> TV > follow the wizard) and try again.

Yes, I already have an IR Blaster set up to work with the STB. I was able to configure it during the Media Center setup, and it works fine in Media Center. After I set that up, I installed Orb and ran that setup. The last part of the Orb setup said that in order to change channels, I would need to configure it in Media Center. Because I had already set up Media Center, I did not do anything else. Do I need to re-run the Media Center setup?

If you can change channels via MCE then you should be able to change it via Orb too, we recommend you to restart Orb/Orb PC and then try again. If this does not work, please let us know the following:

- Is your Win 7 32bit or 64bit?
- Did you by any chance upgraded from a previous version of Orb?. Which EXACT version?
- Were you able to change channels in the previous version of Orb?

This was a clean install of 32 bit Win 7 Ultimate. I know it used to work correctly with Vista, but it was about a year ago when I last used Orb, and I do not know the exact version I was running, but I also was not using a STB then.

Thanks for your response. This issue was there in 2.51.0032 and has been recently fixed in an upcoming version which is expected to be released at the earliest.

Great, thanks! I'll keep my eyes open for the new release!
