I recently configured Emby to use WinTV using my Hauppauge HD PVR. Everything works great! One thing I noticed is that if I close Emby while streaming Live TV, WinTV doesn't seem to release the HD PVR and I need to restart the WinTV service to get it working again. If I use the back button, everything works perfectly. This issue might only apply to PVR devices from Hauppauge because they work a little differently than a traiditional tuner. This would apply to HD PVR, Collossus, & HD PVR II.
