I can't figure out why my TV tuner does not work with Orb?

**** This article is applicable only for 2.0x series of Orb ****
(To know your Orb version, click Orb tray icon - About)

If you are able to stream audio / video files but not Live TV then verify that:

- you have a compatible TV tuner (see: How can I find out if my TV tuner will work in Orb?), detected by Orb and listed under Orb tray > About > System info > Capture Devices

- your tuner has latest drivers installed, if not then update drivers from tuner manufacturer's site.

- your tuners works in its native PVR application

- your tuner is not in use by another PVR application (WinTV, Windows Media Center, etc.) when you are trying to stream Live TV via Orb

80004005 unspecified error: Your TV tuner is either not working or not configured properly or incompatible with Orb. If it is a supported tuner and it works fine on your Orb PC, please send a support request at support.orb.com

- This error usually indicates that Orb cannot access your tuner. Orb will not function with any other third-party PVR application using the tuner, as the tuner cannot be shared. If it does not work with Orb on your PC, it may be due to a conflict with third-party software that may be installed on your system. Suggestion: Try disabling /temporarily uninstall 3rd-party PVR software installed in your system to see if it may be the cause of the conflict with Orb.

- You may have corrupted tuner drivers. Suggestion: Try re-installing your tuner drivers.

- Your anti-virus software had its virus definition (automatically) updated and now blocks the OrbTVBuffer program from executing. Suggestion: Check the list of allowed programs and re-allow OrbTVBuffer.exe (as well as OrbStreamerClient.exe, if other streams also fail)

- Recently, you had some automatic Windows Update that may cause a conflict with the OrbTVBuffer application or the OrbStreamer program which detects audio and video hardware devices on your system. Suggestion: Check in the Add/Remove Programs of your Windows Control Panel for timestamp of Windows updates and try to roll back the update and try again.

- Try to record a Live TV channel via Orb and see if you can play the recorded file locally
